Here is a draft of the blurb for the back cover:
In the United States, telepaths are hunted by the Telepathic Corps, a small, mobile army who can sense when other telepaths are using their powers.
When famous telepath George Wynton is found at the scene of his lover’s murder, novice detectives Olivia and Darcy Morison are charged with finding the real killer.
But the sisters have troubles of their own: under the thumb of a heartless mentor, they are forced to divide their time between helping Wynton and doing other mind-numbing jobs, like finding a gangster’s beloved dog.
Meanwhile, other dangerous elements are at work: a high-powered, secret group called The Twenty is working to make sure Wynton stays behind bars while members of Boston’s telepathic underground are threatening to rise up and break him out of jail. And the Corps has arrived in the city, rounding up telepaths with a vengeance.
No one knows what happens to captured telepaths, but rumors of secret medical experiments and death squads fly through the telepathic underground.
Olivia and Darcy are in danger as well. Trained to keep their abilities secret, they have become experts at passing as normal. They must find the killer and keep their secret hidden while working with the telepathic underground.
