BLUE SKIES TOMORROW, by Sarah Sundin

Helen Carlisle is left widowed, with a small son, when her husband is killed in the Pacific during WWII. To the people in her hometown, she's a brave woman who is giving her time to support the war effort in honor of her heroic husband's memory. But Helen is hiding a secret about her marriage.
Lt. Raymond Novak wants nothing more than to serve his hometown as a pastor, but with the war raging on, and two brothers already in the service, he enlists in the Air Corps--to train pilots, not to be one.
When Helen Carlisle catches his eye, he’s determined to win her hand, but her past fears place a roadblock between them.  His own fears erupt when he’s called to active duty in Europe. Blue Skies Tomorrow moves seamlessly from California to the European theater and back again. Sundin is a master at writing breathtaking scenes of air battles involving B-17 bombers. The final chapters of this novel will have you holding your breath.
Blue Skies Tomorrow is a fitting conclusion to the saga of the Novak brothers. It’s not necessary to have read the first two books in the Wings of Glory series to enjoy this one. But if you haven’t read A Distant Melody and A Memory Between Us, you’re in for a treat. This is a wonderful series.
