18 Long Books That Are Actually Worth the Time Investment

Every editorial product is independently selected by our editors. If you buy something through our links, we may earn commission.

Our TBR (that's "to be read") pile is infinite, but time is (unfortunately) finite. That means a solid book recommendation is a crucial time-saver, especially when considering a hefty read. Trust me, you really do want to know if that 800-page saga is a page-turner before it's too late.

To find which reads are actually worth investing loads of precious reading time, we posed a question to our trusty and super knowledgeable POPSUGAR Book Club: Which lengthy books (350 pages or more) have you read that are actually worth the time investment? As always, the POPSUGAR Book Club community delivered, providing a wide range of recommendations. From classics like The Count of Monte Cristo to contemporary titles (think: The Goldfinch), there's an ambitious book below for every kind of reader.

"A Little Life was excellent! It's a big read . . . but so worth it! It's very emotional, compelling, and thoughtful." — Quand R.

Outlander by Diana Gabaldon
Amazon

Outlander by Diana Gabaldon

"I felt [the Outlander series] was worth it because I love historical fiction/romance/fantasy. It had a little bit of everything and [the main character] Claire is such a strong woman. She's not one of these characters that you're like, 'Why are you doing that?? I would not do that!' She's a strong woman who stands up for herself in a time when women couldn't speak for themselves very often." — Allison R.

The Heart's Invisible Furies by John Boyne

"[The Heart's Invisible Furies] needed all 582 pages to tell you about all of the ups and downs of Cyril Avery's life. You live in Cyril's world, you get to know him and love him and feel for him. I'm so glad I read it, Cyril is now one of my favorite characters I have ever read." — Ashley C.

A Suitable Boy by Vikram Seth

The Signature of All Things by Elizabeth Gilbert
Amazon

The Signature of All Things by Elizabeth Gilbert

"The Signature of All Things by Elizabeth Gilbert is 501 pages. I read it about two years ago, and I keep remembering flashes of it, even now. No other book I've read in the past few years has affected me like that. The minutiae she went into about moss, of all things, fascinated me." — Saara M.

A Court of Thorns and Roses Series by Sarah J Maas
Amazon

A Court of Thorns and Roses Series by Sarah J Maas

"The A Court of Thorns and Roses series by Sarah J Maas, the first fantasy/romance series I've ever read. I was hooked immediately and couldn't put the books down once I picked them up. Seven days straight of non-stop reading, and it was so, SO worth it. I actually wished each book could be longer so I could be immersed in that world longer." — Taylor C.

The Wolf Hall Trilogy by Hilary Mantel

"Hilary Mantel's Wolf Hall trilogy. The last one, The Mirror and the Light, is 700+ pages, but the whole series is amazing! It's taking me ages, but I never want to leave! In general, historical fiction makes great long stories/series." — Liz D.

"At the end, I was feeling so happy and content. Definitely magical."

Salem's Lot by Stephen King
Amazon

Salem's Lot by Stephen King

The Other Boleyn Girl by Philippa Gregory

The Other Boleyn Girl by Philippa Gregory

"[The Other Boleyn Girl is very well written and just an amazing story. It's such a wonderfully different view of the court of Henry VIII. Totally recommend reading it." — Kara S.
