"RiTS" addresses issues of divorce and depression through the journal writings of 13 year old Maurits (Rits). Writing in the journal is a new activity for Rits, and the entries begin short and choppy, but improve as the days go by. Sent to live with his Uncle Crorry during the Summer, it isn't immediately apparent why. Rits is reluctant to address the reasoning even in his writings. The story follows the progression of Rits' relationships with his new friends Rita and Eva as well as the budding of Uncle Crorry from a depressed, out of work and boozing stranger into family. The humor with which "RiTS" is written makes for a fun read, but it can also come at the expense of it's main character. It is an enjoyable read, likely more so for the younger end of the 12-18 spectrum, but whether it is a "Permanent contribution to the genre" - is more difficult to say.
I'm on the fence, but leaning towards nay - looking for other thoughts in the comments.
