Decisions, decisions.............

Having finished my book and up to date on other reading material, it was time to decide what book next.
Do I go back to Richard Holloway which  I'm 2/3rds through, but is a book that I've been reading in splurges as it's one that I've found I need breaks from to "digest things".
Or......
Do I go for Percy Jackson which requires absolutely no thinking at all? 

Hummmm. Well I do have a cold at the moment and the brain isn't really working sooooooo.................
