"Uniquely charming! With her delightful characters, Biller builds an irresistible world inside a Viennese Victorian-era hotel that is equal parts screwball comedy, epic love story, and thrilling mystery. An utterly captivating novel about the power of fate." - Joanna Shupe, USA Today bestselling author of The Fifth Avenue Rebels series

Diana Biller's Hotel of Secrets is chock full of banter-filled shenanigans, must-have-you kisses, and romance certain to light a fire in the hearts of readers everywhere.

During ball season, anything can happen--even love.

It's ball season in Vienna, and Maria Wallner only wants one thing: to restore her family's hotel, the Hotel Wallner, to its former glory. She's not going to let anything get in her way - not her parents' three-decade-long affair; not seemingly-random attacks by masked assassins; and especially not the broad-shouldered American foreign agent who's saved her life two times already. No matter how luscious his mouth is.

Eli Whittaker also only wants one thing: to find out who is selling American secret codes across Europe, arrest them, and go home to his sensible life in Washington, DC. He has one lead - a letter the culprit sent from a Viennese hotel. But when he arrives in Vienna, he is immediately swept up into a chaotic whirlwind of balls, spies, waltzes, and beautiful hotelkeepers who seem to constantly find themselves in danger. He disapproves of all of it! But his disapproval is tested as he slowly falls deeper into the chaos - and as his attraction to said hotelkeeper grows.

"With prose to match the sumptuous setting of 1870s Vienna, Hotel of Secrets is an exquisite and decadent read. Diana Biller breathes new life into historical romance with writing that is singularly lush, deeply romantic, and transportive. Readers will get swept away by the combination of nail-biting intrigue and whole-hearted passion." - Rosie Danan, bestselling author of The Roommate
