book review on einstein's underpants and how they saved the world

I read a book by Anthony McGowan called Einstein's underpants and how they saved the world.

It was about a boy named Alexander who forms a team to battle evil borgia life forms. He puts Einstein's underpants on his head and knows everything! He and his team end up on borgia spaceship and attempts a daring escape. It is a good book for boys and girls 8-13.
