This book was one of my favorites of the series. Amy is SUPPOSED to have fun on a camping trip called Wilderness Adventure, with her bestfriend and boyfriend, Tasha and Eric Morgan but it leads to trouble. Amy and Andy, a guy who is also in wilderness adventure, seems to have a weird connection with Amy. Amy has a large shape of a cresent moon on her shoulderblade, and knows that that's the way she can truly identify herself as a clone of project cresent. But when she sees that Andy has the same shape on his shoulder blade, she needs some 411 because from what she knows, there are only girl clones of project cresent.
