Borderline by Allan Stratton
298 pages; 2010

Printz Honor–winner Stratton (Chanda's Secrets) explores the genesis of and fallout from racial and religious discrimination in this thriller about a Muslim boy's life, which is turned on its head when his father is accused of collaborating with Islamic terrorists in a plot to contaminate the water supplies in New York City and Toronto. But 15-year-old Mohammed “Sami” Sabiri has more to worry about than the resulting media circus and his father's incarceration. How can he avoid being bullied at school? How will his mother support the family after being fired? And are the allegations about his father true or are they the result of a scared community and a government embracing prejudice at its worst? When Sami goes undercover to verify his father's innocence, the story reaches a fist-clenching pinnacle before a conclusion that should defy readers' expectations. ~From Publisher's Weekly

They Never Came Back by Caroline B. Cooney
200 pages; 2010

In a busy school cafeteria, a teenage girl is confronted by a classmate who questions her identity. He explains to the students who have crowded around that the girl bears an uncanny resemblance to his cousin, who was taken away by social services five years ago. Her parents abandoned her, fleeing the country after being accused of embezzling millions of dollars. The students are intrigued, but the girl shrugs off the attention as a case of mistaken identity.

As the days pass, however, the boy refuses to relent and even brings his parents in to back him up. But they are not the only adults involved. An FBI agent who has been working the case these past five years believes that whoever this girl is, she can serve as bait to help the FBI capture the fugitives. ~Publisher's Description

Heist Society by Ally Carter
287 pages; 2010

When Katarina Bishop was three, her parents took her to the Louvre . . . to case it. For her seventh birthday, Katarina and her Uncle Eddie traveled to Austria . . . to steal the crown jewels. When Kat turned fifteen, she planned a con of her own — scamming her way into the best boarding school in the country, determined to leave the family business behind. Unfortunately, leaving “the life” for a normal life proves harder than she’d expected.
Soon, Kat’s friend and former co-conspirator, Hale, appears out of nowhere to bring her back into the world she tried so hard to escape. But he has good reason: a powerful mobster’s priceless art collection has been stolen and he wants it returned. Only a master thief could have pulled off this job, and Kat’s father isn’t just on the suspect list, he is the list. Caught between Interpol and a far more deadly enemy, Kat’s dad needs her help.
For Kat there is only one solution: track down the paintings and steal them back. So what if it’s a spectacularly impossible job? She’s got two weeks, a teenage crew, and, hopefully, just enough talent to pull off the biggest heist in her family’s (very crooked) history — and with any luck, steal her life back along the way. ~Publisher's Description
