What’s the last ★★★★★ book you read?

It’s been a month of (mostly) awful reads for me.  Sure, there have been a few mediocre ones in there too, but I can hardly even remember my last five-star rating!  I actually had to scroll back through my Goodreads history.

Turns out, my last glowing review was for Beauty Queens by Libba Bray, which I finished way back on May 18.

It’s about time for another awesome book.  Any suggestions?
