Kindle readers can already share quotes and recommendations with their friends on Facebook and Twitter, but what if you don't want your entire social network to know you've been reading The Submissive?

Good news—you can now swap those steamy quotes with just your bestie, or your entire book club, thanks to a new Kindle feature that lets you share quotes, highlights, and recommendations with specific people.

The feature is available on the Kindle Android app, and Amazon plans to roll it out to Kindle e-readers and other devices later this year. Just press the share icon at the top of the app (pictured above) and you can send the quote you like via text, email, or messaging apps like Facebook Messenger and WhatsApp.

When your friend receives the message, they can instantly start reading a free book preview right from their phone, tablet, or PC. Best of all, they don't even need to be a Kindle user, sign up, or install the app to see what you sent.

"The perfect quote in a book isn't always the perfect quote for your whole social network," Russ Grandinetti, senior vice president of Kindle, said in a statement. "Now it's easy to share exactly what you want in a Kindle book with exactly who you want. Kindle makes it easy to chat about the books you're reading, whether it's making a recommendation or sparking a conversation about a quote you loved."

Meanwhile on the Amazon front, the online retail giant last week tweaked its ratings system to start assigning more weight to recent reviews, as well as those written by verified purchasers of a particular product. Previously, scores were an average of all the stars a product's reviewers had given it. Hopefully it won't affect those hilarious reviews too much.

Last week, Amazon introduced an upgraded Kindle Paperwhite with a 300-ppi screen and a more readable font with auto-hyphenation, but the same $119 price tag. For more, check out PCMag's full review.
