Starts today and runs through the end of June.

Apparently you gather “achievements” by reading and earn “bragging rights.” Wow, how enticing is that? And in exchange for bragging rights, Amazon gets more data.
In fact, I don’t care to what extent Amazon snoops when I’m reading on a Kindle device or app, but I prefer honesty about what’s going on at a minimum. I did wonder if it’d be like the challenge last summer, when you could earn actual credit toward purchases. But no, just the fun of the brag.
