When devilishly handsome Theodore Montague meets Lily Patterson in Rome, he is quite taken by this pure English beauty. Theo's not looking for a wife, but he needs a nanny for his three motherless children and Lily's the perfect candidate!Lily might feel completely out of her depth in Theo's glamorous world, but from the moment they're under the same roof the spark between them ignites into a passion neither of them can ignore....

• this was a "sweet" read. No sex, not erotic, i dunno if there was "passion"
  That being said, still a good read.
