• Amazon Prime Day runs from June 23 to June 25, 2026, featuring major discounts on popular book box sets.
  • Bestselling bundles from authors like Emily Henry, Sarah J. Maas (A Court of Thorns and Roses), and Jenny Han (The Summer I Turned Pretty) are on sale for up to 78% off.
  • These books are perfect for your summer reading and your long plane rides.

Look at your bookshelf right now, and tell me if you like your selection for the summer. If you checked and realize you have absolutely nothing light, gripping, or utterly binge-worthy to throw into your beach bag… then you might need to do some shopping.

Thankfully, the universe (and Amazon) timed things perfectly. Amazon Prime Day is officially here from June 23 to 25, and while everyone else is busy fighting over air fryers and robot vacuums, I am head-first in the book section. If your reading goal for the summer involves getting completely lost in a story (whether that means swooning on a beach towel, unraveling high-stakes fantasy politics, or feeling like a kid again) the bundle sales happening right now are almost too good to be true.

I’ve rounded up the absolute best box set deals of the event. These aren't just random filler books; they are the popular, screen-adapted, viral phenomenons that I’ve personally devoured and recommended to everyone in my many book clubs. From perfect contemporary romances to iconic fantasy worlds, here are the box sets you need to snap up before Prime Day wraps.
