Girl has always loved hanging upside down, manages to join circus and be trained as a trapeze artist. Her trainer (and later love-interest & husband) catches her flying with her eyes closed and after much convincing, they turn it into a blind-folded act with silver dollars against her eyes and then covered by a blindfold. One mayor of a small town does not believe they are really blindfolded and arranges an accident. One of them is sent off course and the other must hurtle himself into her at an angle that will bring her into the net rather than a deadly impact.
In looking for this book I wondered if my adolescent self could have misunderstood the gender and relationship but MZB’s the Catch Trap doesn’t seem familiar enough.
The book was near Heinlein’s The Puppet Masters in my small middle school library so I believe the author’s name likely started with either an H or a nearby letter.
Try this: The Long Way Down, by Robb White.

Probably not it, but Circus Sequins by Elisabeth Friermood was a circus book I loved. I haven’t read it for 30 years, but I think it has some similar elements!
Sounds like that could be it- thank you!
The Long Way Down by Robb White.
Thank you so much. I have been looking for the name of this book for at least 15 years.
