Robert B. Parker's Booked — Alison Gaylin

Boston PI Sunny Randall investigates a popular book critic on a mean streak . . . only for her to wind up dead, in the latest thriller in Robert B. Parker's bestselling series.

World famous author Melanie Joan Hart asks for Sunny's help in tracking down Book Babe, the screen-name of an enormously popular book reviewer, who has trolled her with a deeply insulting one-star review. This usually wouldn't matter except that Book Babe has thousands of followers, and her unwarranted blast has Melanie's publisher threatening to pull all her books.

But Sunny's investigation reveals that the reviewer and Melanie have a rich history -- in fact, she may even have good reason to hate the torn-up author. And when Book Babe suddenly turns up dead, casting Melanie as a possible suspect, Sunny finds herself in a complicated web, which, if she can't untangle fast enough, might just put a target on her back.
