How to Seduce a Duke, How to Engage and Earl and How to Propose to a Prince - Kathryn Caskie

Very cute historical trilogy based a set up triplets who learn up their adopted father's death they may the children of the Prince Regent and his illegal Catholic wife. In setting out to prove who they are the three end up in love and married to men their new guardians from the Old Rakes Club have set out for them (unknowingly to the girls). You should read them in order to get the best out of the series. And in the end all secrets are revealed (at least the reader).
