Ex Libris
The archive
Free readers get the last 7 days. Members get every plot and cover puzzle we've ever published. Browse back, pick a date, finish the ones you missed.
The weekend
Each weekend we send Members a themed quiz, built from books in your reading orbit. One author, one decade, one genre. In your inbox by Saturday morning.
The search
Members get our web-grounded lane. It looks beyond the catalog and finds books from the foggy half-memories the fast lane gives up on.
The quiet
The site stays quiet. No display ads on result pages, on the archive, or anywhere else you read.
Ask the librarian
Yes. From your Account page, two clicks opens the Stripe billing portal and you can stop renewal right there. You'll keep Member access until the end of the period you've already paid for.
$5 USD per month, or $50 USD per year (that's two months free). Both options run through Stripe. Switch between them anytime from the billing portal.
No. The daily plot and cover puzzles are free for everyone, and so is the last 7 days of the archive. Membership opens up everything older than that, plus the Saturday mega-quiz and the rest of what's listed above.
Your streak history stays. You can keep playing the daily puzzles for free after cancelling. You lose access to the full archive, the Saturday mega-quiz, and deeper AI search, and you'll see ads again.
Yes. We're working on saved reading lists, personalized recommendations, and a reading-history export. Members get all of these automatically as they ship, at the same price. No upgrade or new tier.
Stripe handles all of it. Your card never touches our servers. To update your card or download invoices, use the billing portal from your Account page.
Yes. Email justin@whatisthatbook.com within 14 days of your first charge, monthly or annual, and we'll refund you in full. No questions asked. Full details on the refund policy page.
