I hve recently read a book called 'The true meaning of Smekday) by Adam Rex. It's about a girl (Tip Toucci) who loses her mother during an invasion of some aliens called 'Boovs'. While she's trying to go to Forida to find her lost mother Utopia meets a Boov called J Lo. With him they are trying, not only to find Utopia's mum, but also to save the world from another kind of aliens, Gorgs. You can guess what happens next. Tip and J Lo become friends and find a way to destroy Gorgs.
I will not spoil the end of the book, even though it's clear what happens next. I just want you to read the book, because it's funny, but at the same time touching. You will definetely love this book if you are keen on science fiction, humourous stories and deep meanings!
