I read Alien Tango (#2 in the series) after reading Alien in the Family (#3) so now I know where that new character in #3 came from, and here I first meet Chuckie, another great character. More adventure, wonderful characters and dialogue, and I've mentioned her fun asides before. More problems with family and nasty, nasty villains; and the alligators, Alliflash and Gigantagator, were imaginative and thrilling additions. 
 Highly recommended--again--and I've already ordered #4. And again--adults only.
