The Other Princess by Lacy Williams

It’s a royal twin switch and Luc is falling for the wrong princess…
Princess Margaret hasn’t been to her homeland Glorvaird or the palace where she grew up in over a decade. And for good reason—a secret reason no one knows. But when her twin sister travels across the ocean to the family’s Texas ranch to beg Maggie to trade places with her, she can’t refuse. If Maggie is found out, it’ll be a royal scandal of epic proportions.
Luc Moreno has spent years rebuilding the family legacy his father tore apart. He needs the help of a princess or he’ll risk losing everything he’s worked for.
As Maggie slips back into the world of palace intrigue, power and deception—pretending to be her sister—she finds herself falling for the handsome politician. But will Luc still want her when he discovers her true identity?
