I participated in this last year and had a great time, and even won a few books (which is always fun). New LDSFiction is hosting a challenge to read LDS authors during the month of July (you don’t have to be LDS to participate). They will be giving away prizes throughout the month as well. I never really paid that much attention to it before, but there are a lot of popular LDS authors out there. After last years Trek I even created a shelf on Goodreads devoted to LDS authors, I'm still adding to it and I've got over 100 so far. Below are my book choices for this year, it was hard to narrow it down and I'm sure I'll be updating it as I go.
