Recs if you like The Willoughbys...

A collection of slightly dark, spooky, or existential books for children whose imaginary friend just might have been a ghost, who fantasized about being an orphan, or who would have appreciated the Well for Sensitive Boys to gaze into. A mix of titles from my millennial childhood with some newer additions.

These are works with siblings (borthers/sisters) as its protagonist and heart of the story. Don't need to necessary be blood related or in good term. It can be rivalry, as long as the story have siblinghood as one of the theme. The siblings need to be a fully-fleshed character, not background character and—weird that I need to clarify it—NOT A FUCKING INCEST 🔪

Books that have been adapted as Netflix Originals Feel free to comment any that need adding!
