Timed along with the release of Home (the animated movie made from The True Meaning of Smekday) this sequel continues the friendship of human 12-year-old Tip Tucci and Boov alien J.Lo (whose name was changed to Oh for the film) about a year-and-a-half after they saved the world.
Socially, J.Lo is in bad shape: He's viewed as a villain by his people, who consider him The Squealer because his message allowed their enemy the Gorg to find Earth. On the other hand, the humans view him angrily as one of the recently defeated earth invaders and all-around as a general nuisance.
So when J.Lo and Tip strike on the idea of a trip to see New Boovworld (formerly Saturn's moon Titan) and try to clear his name, what could possibly go wrong? Well, for starters, Mom says NO. And there's that bit about J.Lo being Public Enemy Number One.
It's not necessary to have read the first book to understand this one, but by all means READ THEM BOTH!! This has become one of my ultimate favorite series in the history of ever.
I cannot say enough about the AMAZING Bahni Turpin, who narrates these audiobooks. The noises, inflections, and personality she injects into the characters and story are fantastic - she has brought it all to life in such a wonderful way, that I'm actually afraid to see the movie with someone else's version of these characters.
