(Again, not a sponsored post - I legitimately just want you to know about some of the great books you can get this month! Bonus: use my referral link and you'll get a free book (and I will, too)!)
Here are the books I'm getting for myself this month (yes, more than one because this month is just so amazing!)
The Night Tiger by Yangsze Choo (Flatiron, 2019). I just read this book and it is so amazing that I also selected it as my BOTM because I want to own it. Historical fiction set in 1930s Malaysia with a magical realism twist and unforgettable characters.
The Silent Patient by Alex Michaelides (Celadon, 2019). I haven't read this one YET but everyone is talking about it and I would not be a bit surprised if it's the Woman in the Window of 2019.
Maid: Hard Work, Low Pay, and a Mother's Will to Survive by Stephanie Land (Hachette, 2019). Blurb lists this as Evicted meets Nickel and Dimed. Yes, please!
If nothing else, you can create a free Book of the Month account to see what the book selections are each month because they're often books you'll want to purchase for your library.
