for Dead Investigation by Charlie Price
In this standalone follow-up to an Edgar winner's acclaimed debut novel, Murray Kiefer is a boy who lives in a cemetery and can talk with those buried beneath the tombstones. He'd rather no one knew, but word got out once he helped solve a fellow student's murder. Now people think he's nuts, or want to use his ability for their own ends, or don't care that he might not want to get tangled in another police investigation all over again. But there's been a brutal killing--maybe more than one--and Murray may be able to help unravel the crime, although not without risking his own life, and those of the only friends he has.
