Herzsprung - Brigitte Blobel Uncomfortable book that every child and adult should read. I've read this book ages ago but still remember it very vividly. 15 year old Nina lives with her mom, stepdad and younger stepbrother. When a boy from her school befriends Nina, she starts to fell in love with Florian. Thanks to Florian's friendship Nina finds courage once more to tell someone that her stepfather was sexsually abusing her. And this time to get help.
