Through Waters Deep is my very first Sarah Sundin novel and I really enjoyed it. Taking place right before America entered into Word War 2, it portrays some of the pressure of those that were living in Boston at the time. Starting with the distrust of all Germans, the French and British wanting the Americans to enter the war, and those that did not want the draft to be enforced and who wanted their sons back home made this read full of high tension. With rising threats of a saboteur harming the ships, our heroine, Mary, with Nancy Drew tendencies is focused on finding the guilty party and doing her part to aid in the war. She meets up with old high school buddy Ensign Jim Avery whom she becomes close friends with and he believes her suspicions. Alternating between Boston and Jim’s time on ship acting as a convoy we are given a much more complete picture of the times of an ordinary citizen and the sailors on board during this crisis in American history. The romance was a gradual one and the action at times was nonstop. In regards to the romance, I wanted to at times shake both of them and tell them to open their eyes. When they finally did realize what fools they had been, they sizzled. This was book one and I look forward to book two when we meet Jim’s sister. I received this book for an honest review from Revell Publishing and the opinions are my own.
