This is a two story book. You read one then flip to read the other. Both are 127 pages and take about 2 hrs or less to read.

Star Quest by Dean Koontz
Space & time travel, alternate universes, mutants, bodiless brains - everything a young boy likes. This obviously wasn't my thing. But it wasn't a horrible book if it is what you like.
Tohm awakes to find his body gone and replaced by a machine. He produces a new body for himself and goes in search of his love, Tarnilee. He finds adventure and love, just not where or how he imagined.

Doom of the Green Planet by Emil Petaja

The only reason I read this is because it came with the Koontz book. I never heard of Emil Petaja before.

Another book for young boys, but it was interesting and held my attention. Characters are well written and somewhat likable. Plot is simple.
Shalda was my main problem. She was a smart girl and trained fighter. Yet when she meets a stranger from the sky, it takes no prodding or time for her to tell everything there is about her planet, the people, and the situation there. ( )
