The Forbidden Orchid by Sharon Biggs Waller

Staid, responsible Elodie Buchanan is the eldest of ten sisters living in a small English market town in 1861. The girls barely know their father, a plant hunter usually off adventuring through China. Then disaster strikes: Mr. Buchanan reneges on his contract to collect an extremely rare and valuable orchid. He will be thrown into debtors’ prison while his daughters are sent to the orphanage and the workhouse.

Elodie can’t stand by and see her family destroyed, so she persuades her father to return to China once more to try to hunt down the flower—only this time, Elodie goes with him. She has never before left her village, but what starts as fear turns to wonder as she adapts to seafaring life aboard the tea clipper The Osprey. But now, even if she can find the orchid, how can she ever go back to being the staid, responsible Elodie that everybody needs?
