Animorphs - The Descendants

{I apologize for writing 'Descendants' wrong on the cover- apparently I had not yet discovered autocorrect when I made it XD}
Ray know's she's not just a normal girl. When she was three, she first saw her father turn into a tiger in the backyard. Her 'uncle' sometimes seemed to be talking to this one bird. When her mother told her that she was infused with the same power her parents -Cassie and Jake, her second husband- and her 'uncles' Marco and Tobias, who is apparently a red-tailed hawk?
Full of drama, action, 'romance' and of course animals, Animorphs - The Descendants is about how Ray and Marco's twins, Sam and Martha are warriors- defending the world against the parasitic aliens called Yeerks after the Ellimist wiped the memory of all except the six humans and one bird who are now the Animorphs.
