Color Blind

A shooting at an Orlando, Fla., theme park draws forensic psychologist Jenna Ramey away from her private practice and back into detective work with the FBI in this entertaining first in a new thriller series from Marshall (Chain of Command). After the shooting, gunman Isaac Keaton immediately surrenders himself. Jenna, who has grapheme-color synesthesia, or the ability to perceive color in relation to a subject’s emotional state, deduces that Isaac is one half of the Gemini, a pair of infamous serial killers who have been targeting the East Coast. During her mind games with Isaac, he hints that there’s another killer at large and that he might know something about Jenna’s mother, a sociopath who has threatened Jenna and her family before. In the battle to outsmart Isaac, Jenna proves clever enough without resorting to her synesthesia, which only reinforces conclusions she draws from more conventional clues. Readers will look forward to seeing more of this appealing heroine. Agent: Rachel Eckstrom, Irene Goodman Literary Agency. (Nov.)
