'I think maybe boys have a different way of looking at things. That could be it.' Olivia's best friend, Hal, thinks Fridays are blue, and tangy, like blue lemon sherbert. Olivia thinks he's crazy!.

Friday is just plain Friday - isn't it? And what's even crazier is Hal's funny and mysterious plan to make his sort-of-stepfather, Alec, leave home.

In Hal's weird world, if he can make Alec disappear, everything will be OK. But Olivia isn't sure that Alex is really the problem - can she find a way to change Hal's mind and make him happy again?
