Danny and Shannon Culligan are trapped under the thumb of their alcoholic father. Danny's been in love with his childhood sweetheart, Jennie Martin- a wealthy cottager from Philadelphia- for as long as he can remember while her cousin, Hugh, is smitten with his sister.
As the foursome struggles to surmount the class differences between them, the nation is plunged into World War One, changing all of their lives forever. Danny is drafted into the Army and Hugh enlists in the Navy- defending the home front as a lieutenant at Cape May Section Base Number 9. While Jennie works tirelessly on the Liberty Loans campaign in Philadelphia, Shannon finds herself ensnared in a rum ring operation as the temperance movement ebbs closer to its goal of Prohibition.
A sweeping saga of betrayal, lies, and loss on all sides, Thicker Than Water, challenges readers in its exploration of the age-old question about where one's loyalties lie.

Just how far would you go to protect your family?
