Recommendations

I am... wait for it... going on vacation. Not a "get together with the family for a holiday" type of vacation, either. I am going to South Padre Island to relax by the pool with my Mom and drink margaritas. Now, normally I read everything on my phone, but I am afraid of having my lifeline phone so close to the pool. I am opening myself up for good, pool-side book recommendations. I'll read anything except for horror, but I'd prefer something light to read out while I'm soaking up UV rays.

Thanks in advance!
