After Her


Joyce Maynard - 2013
    Left to their own devices, the inseparable sisters spend their days studying record jackets, concocting elaborate fantasies about the life of the mysterious neighbor who moves in down the street, and playing dangerous games on the mountain that rises up behind their house.When young women start showing up dead on the mountain, the girls' father is charged with finding the man responsible, known as The Sunset Strangler. Seeing her father's life slowly unravel when he fails to stop the murders, Rachel embarks on her most dangerous game yet: setting herself up as bait to catch the killer, with consequences that will destroy her father's career and alter the lives of everyone she loves. It is not until thirty years later that Rachel, who has never given up hope of vindicating her father, finally smokes out the killer, bringing her back to the territory of her childhood, and uncovering a long-buried family secret. As with her novel Labor Day, Maynard's newest work is part thriller, part love story. Loosely inspired by the Trailside Killer case that terrorized Marin County in the late seventies, her tale delves deep into the alternately thrilling and terrifying landscape of a young girl's first explorations of adult sexuality and the loss of innocence, the bond between sisters - and into a daughter's tender but damaged relationship with her father, and what it is to finally trust a man.

The Killer's Cousin


Nancy Werlin - 1998
    His eleven-year-old cousin, Lily, exhibits malicious behavior that escalates from eavesdropping and taunting to "guerrilla attacks" on David's apartment-strewing trash, destroying computer files, gluing CDs into their cases. Consumed by problems in their marriage dating back to the death of their older daughter Kathy four years before, Lily's parents refuse to recognize her disturbing actions and attitude.Expertly paced, the thriller unfolds tantalizingly slowly, as David learns additional details about Kathy's death and Lily's involvement. As the narrator, he also withholds the full story of his girlfriend's death until the very end, which both adds to the suspense and appropriately reflects his longing for privacy and anonymity. His deep-rooted guilt and loss color his thoughts and cast doubt in the reader's mind about his innocence. Everyday details such as David's adjustment to a new school and his interest in "The X-Files" ground the story in reality. Young adults will eat this one up.

Now Ezra is back there and Nyle doesn't want to open her heart to him. Too many times she's let people in, only to have them desert her.Karen Hesse's voice and vision are grounded in truth; she takes on a nearly unharnessable subject, contains it, and makes it resonate with honesty.
