Delicious Decisions

I was just at the library. Now I have a decision to make. Should I:

1) Continue Eiffel's Tower, which is a non-fiction account of the building of the Eiffel Tower specifically and of the 1889 Paris Exposition?

2) Start Except the Queen, which is due in two weeks, and which Charlotte's Library made sound terribly appealing, and half of which is by Jane Yolen, an author I happen to love?

3) Start Lord Sunday which came in today and which is also due in two weeks? It's the final book in the Keys to the Kingdom series, and I've been looking forward to it since finishing Superior Saturday back when.

4)Or should I read Aunt Dimity Down Under, the latest installment in the frothy mystery series I've been reading, a series almost too light even to be called cozy?

I already had to, reluctantly, return Ice unread (Don't worry, I'll put it on hold again) in order to make room for more books.

Hmmmmm...
