Book #1 The Infamous Heir, Book #2 The Rebel Heir.
When the love of Lady Isabelle Fairlyn's life is betrothed
to her twin sister, Isabelle vows to find a suitable
replacement before the end of the season. He must be a
talented dancer, have a keen fashion sense, and be
perfectly dashing in every way. Fallon St. James is the farthest thing
from perfectly anything. As head of the secretive Spare Heirs Society, he
must stick to the shadows...even as Isabelle's friendship pulls him
reluctantly into the light. But when Isabelle gets involved with the one
man who could destroy Spares, Fallon must decide between protecting
his life's work--or risking everything to save the woman whose warm
smile leaves him breathless.
