Birth of the Butterfly (Brides of Blessings #11)
Mimi Milan, Brides of Blessings

Once destined for great things, Shen Wu settled into small town life with the hope of escaping his past. Resigned to live a life of quiet anonymity, he’s worked his way from the position of a lowly blacksmith’s apprentice to the owner of a lauded smitty. Life is perfect—or so he thinks until a foreigner posing as a geisha tries to steal his father’s sword. Unable to resist, he can’t help but get caught up in her cause and enjoys the opportunity of being a sensei once more. However, master becomes student when he realizes he’s not the only one with a thing or two left to learn about life, legends... and maybe even love.
A Brides of Blessings adventure, the secret of the dragon claw necklace is finally revealed in the last installment of this three part saga.
