Do you know who you are? Andy’s life is a puzzle–even to him. He knows he’s a clone, but other facts remain sketchy. Now he’s on a quest to uncover the truth about the ties his “father” has to the organization–facts that jolt Andy back to past events and that ultimately determine his future. Is Andy’s “mother” really dead? Was he ever really kidnapped? Who is really out to get him? The deeper Andy probes for answers, the more he and Amy learn shocking truths about Project Crescent . . . and about their beginnings.

Amy fears the organization is monitoring her every move. That’s what Andy tells her — before he disappears. He says they’ve both been implanted with a chip. Is there anywhere Amy can hide? The answer seems to lie in a computer game. A game into which Amy downloads her consciousness. A game in which fantastic creatures and terrifying dangers lurk at every turn. A game that Amy suspects is being played in real life . . . by someone with sinister intentions. Amy must get to the end of the game — ahead of whoever’s trying to finish her off.

Amy never knew whom Mr. Devon worked for--the organization that's after her, or some other secret government agency. All she knew was that he seemed to be her ally. He always appeared just when she needed help or vital information. But ever since Mr. Devon's death, Amy has relied on her own smarts to survive. And she'll need them more than ever now that a new substitute teacher at school has it in for her. Ms. Heartshorn has a reputation for being demanding. She doesn't tolerate fools or careless work. And her feedback can be . . . well, a little harsh. Amy hates her. But when she learns why Ms. Heartshorn is really at school, Amy totally flips out.

Now that she's discovered the secret about her past, Amy Candler is trying to deal with the reality of who she is. Having an overprotective mother doesn't help. So Amy is thrilled when her mom is swept off her feet by a handsome man. But appearances can be deceiving. Amy starts getting bad vibes about her mother's inquisitive boyfriend. She starts fighting with Tasha, her best friend, who dismisses her worries. She starts meeting with the elusive Dr. Jaleski, who may be able to help her--but only by putting his own life in danger. She starts searching for other "perfect" girls just like her. This time it's up to Amy to protect herself--and those she loves--before it's too late.

Amy thinks being perfect can be a real drag. Everyone expects her to behave responsibly and to use her extraordinary talents for good. But when she meets one of her clones--an unexpected Amy, Number Thirteen, who goes by the name Aly--she gets a taste of normal teen life and wants more. Aly is a reject from Project Crescent. She runs with a wild crowd whose motto is Good Times Now! She convinces Amy to hang loose and have fun. Drawn by Aly's free spirit, Amy rejects her genetic roots. But Aly's carefree ways come at a high cost. . . .

Amy Candler is trying to keep her special talents a secret, but when that means missing out on the trip of a lifetime, even Amy can't resist. Amy can't believe she is in New York, exploring the city and staying in a plush hotel, but before she knows it, Amy is headed straight for danger.

The chilling FINALE of the Replica series! Something is happening to Amy. It begins with the fading of the crescent moon mark on her shoulder. And as reports trickle in from sister clones who are encountering their share of sudden physical problems, Amy realizes that none of this bodes well. How can the Amys be developing genetic abnormalities? How can they be losing their extraordinary powers? How can the deterioration be stopped? Amy is stumped by the questions racing through her head. For so long, she has wanted to be “normal”–but that was before she risked losing everything that makes her special. . .
