Captain of the Heart (The Wild Heart Trilogy Volume 1)

"...you'll need God to protect you if I find out you're a fraud." Little does Léonie, Vicomtesse de Chmbois, realise the perils she will face when she takes her brother's place on a French ship bound for the Pacific under the command of Captain François de la Tour – perils that will endanger her heart as much as her life. Her masquerade as a young naval officer enables her to escape an unpalatable marriage and fulfil a lifelong dream, but it leaves her in danger of destroying her own – and her family's – reputation forever. This is the first book in the Wild Hearts Trilogy.
