A Mortal Heart’s Desire by Lyndsay Constable

Groaning at the very real, sharp pain in his chest, Darcy leaned his elbows on his knees. It was not the deep, merciless water under the ship that caused this brutal ache. It was the rending of his devoted heart.

With the Darcy finances hanging by a thread, Fitzwilliam Darcy decides to journey to America to oversee his late father’s one good investment, certain that Elizabeth Bennet will await his return.
After she turns down Mr Collins’s offer of marriage, Elizabeth Bennet can no longer tolerate her mother’s cruelty and decides to embark on the adventure of a lifetime, certain that it is her only path towards happiness.
A collision of misunderstandings, celestial events, a fake marriage, concealed desire, and natural disasters will either bring Darcy and Elizabeth together or tear them apart on this wild ride.

This is a partnership. Either we both succeed, or we fail together.
