The Muse calls

The writing muse was busy this week. She summoned me and I could not refuse the call. I have writen well but she is overloading me. I have an idea for a young readers book so may have to lay down the big novel and write this other one. Where to turn I am not used to working on several at a time I feel odd doing it.

How do you know which one to write. how do you spread your time?
The werewolf story is shaping nicely now just to figure out what is going to happen LOL.
