A piano virtuoso and his twin sister become rivals for a new spotlight-the adoration of a mysterious French patron-during the hot Parisian summer of 1957.

“An enthralling literary symphony of ambition, desire, and obsession.” -Layne Fargo, bestselling author of The Favorites and They Never Learn

Twins Natasha and Max Kitson have lived their lives on the road, together building Max's career as a world-renowned pianist, famous for bringing even the most stalwart audience members to tears. But when, at age 20, the former prodigy begins making uncharacteristic mistakes, he abruptly cancels his remaining concerts and moves himself and his sister into the home of an enigmatic French patron, never realizing that Henri has been his sister's lover.

In Paris, over the course of one summer, Natasha's long-simmering resentments and Max's deep insecurities drive the siblings apart as each vie for Henri's attentions. But neither twin can have their host entirely to themselves, because while, during the day, Henri woos Natasha with lavish gifts and trips to the ballet, it's Max's music that draws Henri from bed each night.

One part delicious family drama, and one part twisted love triangle, Crescendo is an altogether un-put-downable escape to the concert halls, ballet theaters, and bedrooms of 1950s France.
