This book is certainly different than the others that MZB is known for, the Avalon & Darkover series. This is about a young adolescent boy who grows in in the circus & falls in love with both high-flying & a high-flyer. It focuses both on the relationship that develops between the two young men & the circus itself.
This book would not be considered PC these days because of the youth of the boy, but the some is wonderful & describes a long-gone small-time cirucs community in all it's glory. I loved it. This book is usually very hard to find anymore as it's long out of print.
