Mission:Rising (Mission Trilogy) by Richard Wolfram

In MISSION: Rising, the second of the Mission Trilogy series, Jake rises to opportunities and continues his newly energized faith mission among his peers, some of whom have started to imitate him.
Still desiring to become an astronaut, his future involves guardian angels and confronting the evil in his life in the form of bullies, surfboards launched at him, and wild animals in Alaska. This all takes place while he builds relationships as he seeks to help those around him join him on the new earth when Jesus returns, heaven 2.0. Jake’s challenge has eternal results for him and others.
