Blue Like Friday 

To Hal, Fridays are blue, and tangy, like blue lemon sherbert. Olivia thinks he»s crazy. Friday is just Friday, isn»t it?
Olivia is pretty sure that Hal»s mysterious plan to get rid of his not-quite-stepfather, Alec, is even weirder. But things don»t go quite as either Hal or Olivia expect. Maybe the real problem is even closer to home than anyone ever imagined . . .
This gorgeously written voyage of self-discovery will entrance boys and girls aged 9+.
