Hi, new story here. I know my other one's are still incomplete but I had an idea and I needed to roll with it. It's a CM and TMI crossover. I'm a huge fan of the books and I'm already involve with the new TV show based off them. So here's my new story, Changing Blood I hope you enjoy it

I have added a new character named Cassandra Rogue she's been with the team since season 4 as an additional member.

Chapter 1. Sleepless

Derek rolled over on his bed, checking his clock the illuminate numbers mocking him showing him that it was 2:34 in the morning. He groaned, he was just getting off his medical leave from being held by an unsure for 3 days straight. The dreams were unpleasant and his new condition more like sickness was a curse. He reached out and grabbed his phone, shitting up in his sheets running a hand down his face, he opened his phone. Garcia had written an app for the teams phones that would tell each other if another member was 'online' or awake so they could talk if they needed to. He sighed in relief when he saw that Cassie was up.

'Hey, you up for talking?' He texted her

'Yeah what's up, you okay?' She answered within the minute

'Just can't sleep, nerves about work tomorrow and the dreams' He replied getting out of bed to stretch his legs.

'Want me to call, we can talk about it''

'Sure' Seconds later his phone began to ring, he picked it up.

"Hi" He sighed

"Hey" She said gently, "So you have trouble sleeping again?"

"Obviously, and you too it seems" Her replied padding to his kitchen to grab a drink.

"Well, insomnia is a bitch" She chuckled

"I'd guess, how many hours have you gotten this week?" He asked concerned for his team meet that had trouble getting sleep

"I'm getting an average of 2 hours a night, which is great for me. I should be back to normal sleep next week, I swear my insomnia screws with me for a week and then I can sleep normally for the next month. It's like I have two periods." She ranted.

"You should've called one of the girls to complain about that." Derek chuckled., unscrewing a bottle and chugging it down.

"What the hell are you drinking at this hour?" She asked confused.

"It's just juice" He lied, putting the container that contained a red liquid back in the fridge concealed in a cabinet.

"Okay." She chuckled. "You think we'll have a case today?"

"Knowing my luck we probably will" He laughed heading back to his bed. Savannah was working the graveyard shift at the hospital so he had the house to himself. She laughed over the phone.

"Well you should probably try to get some more sleep, I'm going to spend the rest of my night doing who knows what before making my 2 gallons of coffee for the day."

"Okay." He sighed. "Thanks for just talking to me, you're a great friend"

"Correction" She grinned down the phone, "I'm an awesome friend, now go get some sleep." She hung up on him. He sat on his bed and reflected back on the recent effects that had changed him and his life for the worse.

Derek groaned his eyes blinking open. He saw darkness and only darkness, the last thing he remember was getting hit in the back of the head, the team was tracking an unsub that was drawing their victims of blood, and it looked like he was going to be next. He had been pursuing a lead that lead him to a conversation with a handsome young man with dark hair and blue eyes, he seemed to be in his mid 20s. Too young to be their unsub, but age was always the hardest to profile so he wasn't surprised that their had not profiled the correct age group for this killer. He scanned his surroundings and heard some shuffling in which he guess was the far corner. He was tired to a chair in the centre of a large room, it looked like a warehouse of some sort.

"I know you're there." He called. "We can talk this out." He had to let the unsub know he was in control, had to keep him in control so he wouldn't kill him out of rage.

"There's no talking." the man said walking up to him. "Only feeding."

"Feeding?" Derek asked confused.

"Do you not remember me turning you?" The man asked. "I made you more than human, a more powerful being that ascends human kind." He grinned. Derek was able to see that his incisors were longer than all his other teeth, they were fangs, and why could he see so well in the dark?

"What did you do to me?" He asked in a cautious tone.

"Do you not remember the first time you woke up young fledgling?" He asked.

"Excuse me I'm old-"

"Ahh." The man interrupted him. "You are mistaken there, I'm over 100 years old."

"That's not possible." Derek said gently, this man clearly had some strong delusions.

"It quite is, remember you're supposed to be dead now" He smiled creepily at Derek.

"Huh?" Derek asked confused.

"Think back" The mans voice suddenly turned melodic and hypnotic. "Think back to when you first woke up my young one."

Derek's mind snapped back to a few hours earlier, he had woken up in the same room he was in now except something was in his mouth, it was the unsub's arm. He pulled away and swallowed nervously, that was his mistake. He felt a coppery tasking liquid go down his throat and then he saw the mans arm, the can had a cut on his arm. The unsub made Derek drink his blood. Derek stared in horror, he had drunk someone's blood, be it killer or not he had drank blood.

"Welcome to your new life" The man spoke raising a knife and before Derek had time to react the man had slit his throat.

His mind snapped to another memory that was temporarily lost from him, he remember waking up and being starving, he bit onto a bag of cool red liquid and drank it down, it was delicious and cured his hunger. After that he was knocked out again.

"What did you do to me?" He asked the man in shock.

"I turned you, welcome to being a child of the night. Welcome to the life of a vampire" He grinned.

"A vampire?!"

Derek put his face in his hands, that one fateful day had changed him forever, he was a monster, a killer, not human. He was. A vampire.

So that's it so far, I seem to have a thing for change poor Derek into something he''s not in the show. Oh well, as always I adore reviews they're amazing. Constructive criticism is alway welcome. As always, see you when I decided to actually write and upload the next chapter
