What Goes Up by Katie Kennedy

Eddie has a chance to escape his life. He is one of several candidates chosen to be tested for one of two positions in NASA's secretive Interworlds Agency. The testing is anything but normal, but then so is the job.

Eddie feels pressure to separate himself from his criminal father. Eddie's  beloved grandmother raised him and taught him to all that she knew about science and the world. He still mourns her recent passing.Rosa is one of the other candidates. Her parents are highly successful scientists. She feels the pressure to do well.

During the testing, Eddie provides interesting, unconventional responses. His troubled past bothers the higher ups who do not quite trust him. Eddie struggles to not end up proving them right.

Then a life changing event happens. Visitors from beyond our planet arrive. From another world, another dimension? It is a historical event and Eddie and Rosa are right there when it happens. With their instructor Reg as a guide, the teens may be the only ones who can deal with the visiting beings to our planet.
