They Came From Below by Blake Nelson

Seventeen-year-old Emily comes to Cape Cod every summer to spend time with her scientist dad. She’s made a really close friend there, Reese. Emily and Reese are prepared to spend another lazy summer together at the beach and other local hangouts. Their prime objective? Get boyfriends! Well they meet two really great looking guys, Steve and Dave, who behave a little oddly, but hey, they claim to be
foreign exchange students, so that makes sense, right? But strange things happen when Steve and Dave are around. They miraculously heal injuries, and they can talk to any living thing. Weird! Well, Steve and Dave aren’t really foreign exchange students, but they’re not from around here either. They’re aliens who have come from the sea to rescue a friend and in the process offer a warning about global pollution. This book is funny, exciting and has a bit of a message,too.
