In Lieu of a Princess - Meredith Bond

Someone wants the prince and princess of Aachen-Düren dead.

When the brother and sister disappear, it's left to a complete stranger to assume the identity of the princess fooling the Queen of England and all of Regency Society. What Lucinda North didn't realize when she agreed to the scheme, was that someone would try to kill her too.

 Anthony Melfield would rather not waste his time helping a spoiled princess learn how to conduct herself. He would certainly rather not have to return to society after a heartbreak. And he most definitely would rather not have feelings for the princess, no matter how sweet, funny, and beautiful she is. To top it all, he would much rather not have to use his skills to save her life and figure out who wants her dead.

In this tangled web of hidden identities, a princess on the run, and three lives at stake, friendships are made and enduring love is discovered.

This is the first book of a three book mystery - the mystery spans all three books of the series. Each one has its own happily ever after.
