This book is 8 years in the making. Started out as my adult debut, transformed into this weird, tense, and dark exploration of the generational curses we are handing off to young people around the world. I’m so proud of it.

A graphic with a white brick wall background with a thin gold outline. Along the top it reads “Rainbow Crate Presents” with a rainbow icon between crate and presents. Underneath that it says “Nico Di Angelo Adventures” in black font. Below this, black font reads “Endpaper Reveal”. In the middle of the graphic is a 3D mockup of the front endpaper of The Sun & the Star. Text at the bottom reads “jacket + edges by @/alessia.trunfio”, “hardcase art by @/giulia_blue”, and “endpapers by @/tienwashere”.
