Two women--bound by blood, torn apart by circumstance--find together that true strength comes in many forms. In 1911, Mabel MacGinnis is Europe's strongest woman and has performed beside her father in the Manzo Brothers Circus her entire life. When he dies unexpectedly, she loses everything she's ever known and sets off in the company of acrobat Jake Cunningham in hope of finding the mother she thought was dead. Isabella Moreau, America's most feted aerialist, has given everything to the circus. But age and injury now threaten her security, and Isabella, stalked by old fears, makes a choice that risks everything.
