Spring: 2018 - The Royal Romance, Book 3

Summer: 2018 - Rules of Engagement: Newlyweds

RoE Newlyweds takes place before TRR book 3 or at least certain chapters take place before other chapters. Because in Newlyweds, at the housewarming party, if you married Leo, both Constantine and Regina come. Leo mentions Liam is having girl trouble = their reason for not picturing him (which I thought meant the events of TRR book 1, and maybe Constantine and Regina visited Leo/Katie during the time the court went to Lythikos because we only see the rest of the characters minus Constantine and Regina).

Constantine and Regina are not present when Leo buys the boat and they announce Katie is pregnant with twins. (Which is the last chapter of Newlyweds, I think, so if a few months happened between the housewarming party where she finds out she's pregnant to the surprise boat gift, it could be possible for RoE:N last chapter to happen after TRR3's chapter of Constantine's death.
