First of all, here's the front cover.
My first impression of the cover was that it was a little overly drama-romance-ish. Also that I really liked the girl's hair.
Aaand because I'm bad at synopses, here is what the back cover says...
"It is 1941 and America teeters on the brink of war. Handsome and outgoing naval officer Ensign Jim Avery escorts British convoys across the North Atlantic in a brand-new destroyer, the USS Atwood. On shore, Jim encounters Mary Stirling, a childhood friend who is now an astute and beautiful Boston Navy Yard secretary.
When evidence of sabotage on the Atwood is discovered, Jim and Mary must work together to uncover the culprit. A bewildering maze of suspects emerges, and Mary is dismayed to find that even someone close to her is under suspicion. With the increasing pressure, Jim and Mary find that many new challenges--and dangers--await them."
Like many back-cover synopses, I have a few disagreements with that one and how it does or does not represent the book. But I won't bother critiquing it... I'll just move on.
