So you have Christmas money to spend on yourself or others and want to support your local chimerical jaguar! Here's a quick holiday shopping guide. It's evergreen!
Young Kids
I have coloring books and chapter books: the Laundry Dragons (rhyming picture book!) and the Vinny the Armadillo series (chapter books, for reading aloud to small children). The Laundry Dragons is just sweet/cute pictures and rhymes about dragons who live in socks in your laundry room; Vinny, on the other handle, tackles the difficulty of making friends in book 1 and of being afraid of the dark in book 2.
Junior High/Middle School
I've got junior high/middle school covered, too, with Marda's story, which is like Narnia meets Anne of Green Gables and Harry Potter. Marda lives on a shattered world of floating islands, and goes to a school to become a healer of cracks in the world. Or she will, once she gets over her reticence about being a heroine.
Late Junior High/High School
Getting into late junior high/high school, I have my cozy wholesome LitRPG about Haley and Nana, which starts with Haley's Cozy System Armageddon (or you can just grab the bundle). Haley welcomes the system apocalypse that grants everyone magical powers, hoping to become a wizard... but her own nature leads her elsewhere, by way of a lot of calligraphy, quests, and baking with her grandmother and That ThomasCat.
College+
Slightly older? College to adult, I have my cozy science fiction series, the Dreamhealers Saga, about two aliens attending college together, and having normal college-age problems (but in space, with aliens!) Or if normal science fiction's your thing, step sideways in the same universe into the space opera adventure, Earthrise, about Reese and her failing merchant vessel concern, and how she gets swept up in large events with pirates and politics...
If fantasy's more your giftee's jam, try An Heir to Thorns and Steel, a breathless epic about a student swept up in good vs evil struggles.
