Amy is off to Paris--the City of Light! She can't wait to go to the top of the Eiffel Tower, to walk along the River Seine, and to see the glass pyramids outside the Louvre museum. But there's one sight she wasn't counting on. Andy! Amy fell for Andy last summer and was shocked to learn that he, too, was a clone. When Andy disappeared, Amy didn't know what to believe about him. Now she spots him at a café. Or thinks she does. . . . Is Andy really in Paris? Is it the same Andy? Is it one of his supposed clones? One thing's for sure: If Andy's around, danger isn't far behind. Amy couldn't trust Andy a year ago, but all she knows now is that she has to find him no matter what!

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 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 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.

Amy is going back to the place where she was born--Washington, D.C. It's a class trip to take in the historic sights of the nation's capital. Sure Amy's uneasy about traveling to the home turf of the people who funded Project Crescent--the reason she's alive--and is in constant fear of being captured. But it's a chance to connect with her roots. After all, what could go wrong? Well, Amy's mother is a class chaperon, and for her the trip stirs up memories. Memories of working in the top-secret government program to develop clones. Memories of a loved one battling a rare genetic disorder. Memories of betrayal, and a decision that would forever change her life. And now the trip back to where it all began pits mother and daughter against an enemy both old and new.

Amy’s encounter with dinosaurs and cave dwellers—and aliens—was pretty wild. Now her quest to stop the spread of the infectious bacteria gets even more bizarre as she agrees to take another perilous voyage. A voyage inside a plague-ridden human body. If Amy survives being injected into this complex landscape where good cells are waging battle against bad cells, she could save millions of lives. But it’s a do-or-die world in there. . . .

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. . .
