The 20 best-selling Amazon books from 2015.

The summer break is a time to hang out with family, relax, sleep in and eat too much ice cream.

But more importantly, it’s a prime opportunity to catch up on all the books you didn’t have time to read throughout the year (despite your good intentions).

If you haven’t sorted out your summer reading stack yet, you’re about to get all the inspiration you need because online store Amazon has released its list of best-selling books from the past 12 months.

Amazon’s 2015 best-sellers

1. The Girl on the Train by Paula Hawkins

A psychological thriller about Rachel Watson, a woman who witnesses something shocking during her daily train commute and after notifying police, becomes involved. According to just about everyone, it’s on par with Gone Girl.

2. Grey: Fifty Shades of Grey as Told by Christian by E.L. James

As if the original trilogy wasn’t enough to satiate Fifty Shades fans, E.L. James released a “retelling” of her erotic (hmm) love story — this time, from the perspective of Christian Grey. It was even released on the character’s birthday.
