Oh, sibling adventures are my jam! 'The Unwanteds' by Lisa McMann isn’t exactly brother-sister, but Alex and Aaron’s twin rivalry-turned-redemption arc in a magical world is packed with emotional punches. One’s artistic, the other’s a rule-follower—their clashes and eventual teamwork had me hooked. Then there’s 'Greenglass House' by Kate Milford. Milo and Meddy (disguised as siblings) solve mysteries in a smuggler’s inn, blending folklore and cozy danger. The chemistry’s more subtle, but the way they decode puzzles together feels like a warm hug.

For a wilder ride, 'The Mysterious Benedict Society' has Reynie and Kate, though not blood-related, operating like siblings—brainy, brave, and endlessly loyal. The series celebrates found family, which hits just as hard. And if you’re okay with graphic novels, 'Witch Boy' by Molly Ostertag features Aster and his sisters navigating magic and gender roles—quietly revolutionary with gorgeous art.

If you're hunting for sibling adventures with that 'Percy Jackson' vibe, let me gush about 'The Kane Chronicles' by Rick Riordan first. It's like Percy but with Egyptian mythology—super fun! Carter and Sadie Kane are this estranged brother-sister duo who reunite to battle gods and uncover family secrets. The banter between them is chef's kiss, and the way they play off each other’s strengths (Sadie’s sass vs. Carter’s cautiousness) gives major 'Annabeth-Percy' energy. Riordan’s trademark humor is there, too—expect talking crocodiles and chaotic magic.

Another gem is 'The Blackwell Pages' by K.L. Armstrong and M.A. Marr. Twins Matt and Laurie discover they’re descendants of Norse gods and get dragged into Ragnarök-level drama. The dynamic feels authentic—they argue, protect each other, and share this unspoken bond when things get wild. Bonus: Loki’s kids are side characters, and they steal every scene. For something darker, 'Lockwood & Co.' by Jonathan Stroud isn’t siblings, but Lucy and Lockwood’s found-family teamwork might scratch the itch.

You’ve gotta check out 'The Adventurers Guild' by Zack Loran Clark and Nick Eliopulos. Zed and Brock aren’t siblings, but their bond is so brotherly it counts—think reckless bravery meets sarcastic backup. The dungeon-crawling action and medieval fantasy setting make it feel like a D&D campaign gone epic.

Also, 'Serafina and the Black Cloak' by Robert Beatty pairs Serafina with her friend Braden, who bicker like siblings while unraveling creepy mansion mysteries. The Southern Gothic vibe adds a fresh twist. And don’t sleep on 'Theodosia Throckmorton'—while Theo’s adventures are solo, her brother’s occasional appearances add hilarious chaos. Siblings in books just get that mix of annoyance and unwavering support, y’know?

What is the best brother and sister adventure book series?

The 'Percy Jackson & the Olympians' series by Rick Riordan instantly comes to mind when talking about sibling adventures. Percy and Annabeth might not be blood-related, but their bond feels just as strong, if not stronger, than many actual sibling pairs in literature. The way they navigate Greek mythology, face gods and monsters, and grow together through chaos is both heartwarming and thrilling. Riordan nails the balance between humor and high stakes, making their dynamic unforgettable. If we're sticking strictly to biological siblings, the 'Kane Chronicles' (also by Riordan) is another gem. Carter and Sadie Kane’s banter and teamwork as they dive into Egyptian mythology is pure gold. Their contrasting personalities—Sadie’s sharp wit and Carter’s steadiness—create a dynamic that feels authentic. Plus, the audiobook versions with dual narrators add so much life to their relationship. It’s rare to find a series where siblings feel this real, with all the squabbles and loyalty intact.
