Altered by Jennifer Rush

Kindle  Nook

Anna doesn't know when the boys came, or why the boys are in basement; but she goes down every night, to talk to Sam and Trev.  Even though she works with her dad doing blood tests, and recording other test results, she cherishes her nightly visits with them. When the government agents show up to take them away, she's willing to leave with them to find answers.

I'd wanted to read this book for some time, but knowing it's the start of a series made me hesitate, and I was right...I'm sucked in now.  Only two of the trilogy have been published, with the third set to release in January, 2015. Not too long to wait, but long enough.

Altered is a fast paced chase/adventure/survival book that I think my girls will enjoy.  I could maybe talk a few boys into reading it, but the cover is certainly for girls, as is Anna's POV. There are a lot of chases, because the group is on the run from the people who "created" the boys. Shoot outs, memory loss, flashbacks, a little romance, and a new series set up, will appeal to quite a few of my students.

Goodreads summary:

Everything about Anna’s life is a secret. Her father works for the Branch at the helm of its latest project: monitoring and administering treatments to the four genetically altered boys in the lab below their farmhouse. There’s Nick, Cas, Trev . . . and Sam, who’s stolen Anna’s heart. When the Branch decides it’s time to take the boys, Sam stages an escape, killing the agents sent to retrieve them.

Anna is torn between following Sam or staying behind in the safety of her everyday life. But her father pushes her to flee, making Sam promise to keep her away from the Branch, at all costs. There’s just one problem. Sam and the boys don’t remember anything before living in the lab—not even their true identities.

Now on the run, Anna soon discovers that she and Sam are connected in more ways than either of them expected. And if they’re both going to survive, they must piece together the clues of their past before the Branch catches up to them and steals it all away.
