Why Do All the Library Requests Always Come at Once!

The Darkness That Comes Before  - R. Scott Bakker Ancillary Justice - Ann Leckie Iceland's Bell - Philip Roughton, Halldór Laxness The Kingmakers - Susan Griffith

So I just received my email notification that these 4 books are now ready for me to pick up!  They always seem to come in batches instead of one at a time.  Most are long reads as well, so it looks like I'll be pretty busy :D

 

Any suggestions of which one I should start first???
