SYLO by D.J. MacHale

Summary:(from goodreads) Fourteen-year-old Tucker Pierce prefers to fly under the radar. He’s used to navigating around summer tourists in his hometown on idyllic Pemberwick Island, Maine. He’s content to sit on the sidelines as a backup player on the high school football team. And though his best friend Quinn tells him to “go for it,” he’s too chicken to ask Tori Sleeper on a date. There’s always tomorrow, he figures. Then Pemberwick Island is invaded by a mysterious branch of the U.S. military called SYLO. And sitting on the sidelines is no longer an option for Tucker, because tomorrow may never come. It’s up to Tucker, Quinn, and Tori to uncover the truth about the singing aircraft that appears only at night—and the stranger named Feit who’s pushing a red crystal he calls the Ruby that brings unique powers to all who take it. Tucker and his friends must rescue not just Pemberwick Island, but the fate of the world—and all before tomorrow is too late.
Review: I have been a fan of D.J. MacHale's books for a long time so I was excited when I discovered that he was releasing a new series. This one did not disappoint. There was a lot of mystery and action that had me hooked. I liked the main characters, especially Tucker and Quinn. They were different but their determination to uncover the truth made them strong characters.  The way the book ended made me very interested to see where the next book is going to lead, which isn't going to be released until next year.  There were a few things that happened that I wasn't happy about but I am hoping there will be a better explanation in the next book. This was one of those books where just when you think things can't possibly get any worse for the characters it does. It kept me on the edge of my seat and I am really excited to read the sequel.
