30 Novellas in 30 Days

I'm trying to read 30 short books in 30 days this month.  So far I've read 10 and today is the 11th so I'm only 1 book behind!  All the books I've read so far are on my 30 Novellas in 30 Days shelf.  I'm not sure what my next book will be...maybe A Monster Calls by Patrick Ness now that I've got a copy from the library.
