Close Protection by Emily Hayes

One night. No names. No regrets—until she walks in as your new bodyguard.

Dr. Ivy Monroe never planned to fall into bed in a hotel with a mysterious stranger the night before entering witness protection.
She especially didn’t plan on that stranger turning out to be Detective Julia Scott—the very officer assigned to keep her alive.
Ivy’s testimony could bring down one of the most dangerous criminals in the city. Julia’s job is to protect her at all costs. But between the close quarters of a safe house and the unresolved heat from their one-night stand, sticking to the rules gets harder by the hour.
They can’t afford distractions. But some sparks are too strong to smother—and the only thing more dangerous than falling for each other might be not falling at all.
