Black Hole Report [PDF ebook] 

This engaging early chapter book is perfect for capturing interest and engaging reluctant readers. It revolves around the fun and humorous adventures of two alien brothers, Eek and Ack from the Great Goo Galaxy. In this title, Ack has to write a school report about black holes, but doesn’t know where to start. Eek’s plan to visit a black hole sounds like a good idea at the time, but the fluffy, overfriendly reception they get from creatures on the other side of the black hole soon makes them want to head for home.
