In the previous book, Hero, Saturday and Trix set off a chain of events that leads to a massive flood, but we only saw Saturday's side of the story. Trix had quite the adventure after he left his family behind. Caught up in Saturday's massive flood, he finds himself underwater and off on a grand new adventure.
Wishing on a passing star sets off a series of events that will ultimately lead Trix far from home, but bring him right where he was heading at the same time. Along the way he meets quite a few pretty fun and amazing characters - grandpa cat was a favorite - and has to pass what seems like a series of tests. Yes, good old-fashioned tests to see if his heart was pure and willing to do what was right.
This was a fun story, but a little short. I wish the tests had been a little more subtle. The format of them was nice, but they were here and then gone again so very quickly.
