Rainbow of Promise is a heartfelt, old-fashioned love story set in the midst of World War II, following the budding romance between Sadina “Sadie” Wagner, a confident and vivacious young woman, and W.E. “Bill” Walraven, a soft-spoken Southern gentleman stationed in Enid, Oklahoma. The story unfolds slowly but sweetly, capturing all the nervous first encounters, jitterbug dances, longing glances, and yes, plenty of sizzling chemistry. It’s nostalgic in all the best ways—like slipping into a vintage movie where the world is complicated, but love is pure.

What stood out to me first was the writing style. It’s simple but rich with period detail and genuine emotion. The dialogue pops without trying too hard, and there’s this easy rhythm to the prose that makes the whole book feel like you’re listening to someone tell a story.

Now, Sadie. She’s a force. Flirty but grounded, fun but not flaky. She’s bold enough to joke about being picked up on a street corner and sweet enough to bring a man to his knees with just a smile. Her scenes with W.E. practically crackle with energy, especially their first dance. I appreciated that the author gave her complexity—she’s not just waiting around for a man; she’s got her own hobbies and she’s protective of her independence. There’s a particularly lovely scene where Sadie turns down an impromptu dinner date with W.E. because of a club meeting—and you can just feel the tension. Her wanting to say yes. His quiet heartbreak. That push-pull dynamic is so well done.

And then there’s W.E.—Bill. This man is a walking romance novel. Polite, a little shy, smells like Old Spice, and dances like a dream. But he’s not just charming. The author gives us these lovely inner monologues where he questions whether he’s “good enough” for Sadie, whether it’s right to fall in love with war looming overhead. That kind of vulnerability made him real for me. And when he takes her to dinner at the Skirvin Hotel and orders champagne and lobster I swooned a little. But my favorite part was the way he watched her dance. That kind of longing—that ache—you can’t fake that in writing.

This book is for readers who love slow-burn, tender romance with real emotional stakes. It’s for anyone who’s ever believed in fate or had their heart flip over a well-timed glance. It might be a little idealistic at times but that’s kind of the point. Life is hard. War is brutal. But falling in love—falling madly in love—makes all of it worth it. I’d recommend Rainbow of Promise to fans of historical romance, lovers of the 1940s vibe, or anyone just needing a little hope and heart right now.
