Alfie & the Aliens of Area 51

Thirteen-year-old Alfie is gradually making the transition to a life in LA, having recently moved from London. Slowly coming to terms with the recent loss of his mom, he is beginning to make new friends and enjoy a new life of beaches, pizza, sitting in traffic, and the complexities of middle school.
Just when things look like they are settling down, he learns that he must attend an eighth-grade adventure weekend on Catalina Island. This remote and beautiful island, off the California coast, is an activity-sports paradise if you like extreme water sports. Alfie is not a fan of anything extreme. Little did he know that the island was also a UFO hotspot, and his visit would lead to the discovery of an alien artefact. That revelation would set in motion a chain of events that would take him on the journey of his life.
Accompanied by the maverick Tally and child-genius Milos,
Alfie is pursued by the mysterious strangers Dark and Cooger to Roswell (ground-zero for alien encounters), then to Skinwalker Ranch (a top-secret research base), and finally to Area 51 (the site of the greatest US government cover-up in history). What he discovers not only shakes the core of who he is and what he believes but also the very meaning of life and the universe itself.
