Within the Mind by Alice Winters

Seneca is the complete package. He’s smart, sexy, and confident, much to Chevy’s annoyance. They’ve worked with each other for two years, and even though Chevy might secretly find his partner charming and attractive, playful harassment is all they have.
Chevy was born with a unique gift that allows him to go into the memories of others. As detective, he uses this ability to find peace for victims who have been hurt or attacked. He delves into their memories and can pick out minute details that will help them put the criminal behind bars.
But neither Chevy nor Seneca are prepared when they are asked to go into the mind of a serial killer in hopes of finding survivors. They are even more unprepared for the monsters they find inside the man’s mind. Drawn into a memory where it’s hard to figure out where the truth exists, they realize that there may be more to the serial killer than they originally thought. The dark world draws the two men together in a way they never dreamed.
It will take everything Chevy and Seneca can give to stop the darkness that could consume their minds. As the two are forced to face what is keeping them apart, together they realize that there’s more to the mind and heart than either of them know.
