"A spider-obsessed killer is hunting Atlanta prostitutes.  Luckily, pregnant FBI special agent Kimberly Quincy has a sense of humor and a thick skin (think Frances McDormand in Fargo) as she chases a villain who calls himself Dinchara—it's an anagram for arachnid.  Despite his ridiculous alias, he's seriously scary and flashbacks to his abusive past achieve a ripped-from-the-headlines authenticity."  Grade:  B

"Lisa Gardner returns with another entertaining thriller featuring Kimberly Quincy, a special agent with the FBI and one of the author’s most likable characters. SAY GOODBYE is a haunting story that might challenge readers with its dark subject matter, but pays off in its fine execution. Quincy investigates the case of a murdered prostitute, which leads her onto the trail of a serial killer who preys on children. Gardner has consistently delivered in recent years, but she’s gone one better with SAY GOODBYE."
— David Montgomery, Chicago Sun-Times

"Absorbing.   Gardner keeps the surprises coming to an explosive conclusion..." 
—Rocky Mountain News

"Gardner knows how to keep the pages turning." 
—Portsmouth Herald

"Devastating and completely chilling." 
—4 1/2 stars Jill M. Smith, Romantic Times

In bestseller Gardner’s engaging if highly disturbing 10th thriller, Delilah Rose is a Georgia prostitute familiar with pregnant FBI Special Agent Kimberly Quincy (“beautiful, brainy, and pedigreed”) through Kimberly’s well-publicized nabbing of the Eco-Killer in The Killing Hour (2003). Delilah asks the detective to investigate her friend Ginny Jones’s possible abduction by a creepy-crawly john who calls himself Dinchara, an anagram of “arachnid.” Delilah, however, turns out not to be who she claims she is, and her ties to the spider-obsessed killer are more complicated than she’ll admit. As the missing persons count rises, some readers may have trouble keeping track of the time sequence amid the shifting points-of-view. Still, Gardner delivers a satisfying resolution in line with what her fans have come to expect: a suspenseful freak show wrapped up with a neatly tied bow.

In the latest Kimberly Quincy thriller, the FBI special agent is five months pregnant. Most women might be thinking about taking things a bit easy, but not Quincy: not only is she still working full time but she also stumbles into what might be the biggest case of her career (and, as regular readers know, she has already tackled a few big ones). A serial killer is targeting young women. This in itself isn’t so unusual, but here’s the twist: he is, or so it appears, using spiders as murder weapons. Kimberly is convinced she is on the trail of a psychopath, but without any bodies or hard evidence, she is having a difficult time convincing her superiors she isn’t on a wild-goose chase. In her last few novels, especially GONE (2006) and the excellent HIDE (2007), Gardner has really hit her stride, and this one, if not her best, will surely be a surefire hit for her fans—and, in fact, for all readers who likes their thrillers suspenseful, fast paced, and just a little creepy (OK, a lot creepy).

"SAY GOODBYE is a novel that you won’t be able to put down once you start— however, it’s disturbing, and on one level so tragically sad that I found myself with tears in my eyes at the end.  For a top-notch novel of suspense, do not miss SAY GOODBYE—another phenomenal novel from the pen of Lisa Gardner."
—Terrie Figueroa, Romance Reviews Today

"SAY GOODBYE should have a warning label: 'Read only in a well-lite room that has first been thoroughly checked for spiderwebs.'  Then, you can settle back and get caught up in a...stunner of a suspense novel." 
—Jeff Nix, Tulsa World

"Lisa Gardner has done it again.  And by 'it' I mean written a book that's likely to give you nightmares." 
—Laura L. Hutchison, Federicksburg (VA) Free Lance-Star
