suggestions containing little to no mention of food/body weight/etc., suitable for a 15y/o

so, a loved one of mine has been struggling with an eating disorder, and i want to give her some books to keep her busy while shes in hospital. i dont want to accidentally give her anything that could trigger her or make her feel worse, so i would appreciate your help in finding something that doesnt discuss body image, fatphobia, or really even food in general. Thank you in advance <3
