Tangible - Dreamwalkers, #1

Dreams don't come true, but nightmares do. Zeke's poor judgment with his last dream student resulted in a fatal catastrophe his secret organization is still struggling to conceal. So when his employers order him to mentor the potential dreamer who just showed up on scans, neither Zeke nor his team is sure that's the right move. They're even less sure when they meet the woman whose supernatural nightmares created a swarm of murder-thirsty vampires.
Maggie is terrified-and crazy powerful-and has the potential to be deadly if not controlled. What's worse, she's got an accidental bond with Zeke, and when students bond intimately with their mentors, it can have disastrous consequences, as Zeke has already experienced firsthand. A student like Maggie requires careful handling if she, her mentor, and lots and lots of oblivious civilians are going to survive.
But first Zeke and his team have to convince her she's no longer dreaming. Warning: Title contains lots of cussing, pop culture references and monsters with nasty, big, pointy teeth.
