I've Got Your Number by Sophie Kinsella

Poppy Wyatt has never felt luckier. She is about to marry her ideal man, Magnus Tavish, but in one afternoon her “happily ever after” begins to fall apart. Not only has she lost her engagement ring in a hotel fire drill but in the panic that follows, her phone is stolen. As she paces shakily around the lobby, she spots an abandoned phone in a trash can. Finders keepers! Now she can leave a number for the hotel to contact her when they find her ring. Perfect!
Well, perfect except that the phone’s owner, businessman Sam Roxton, doesn’t agree. He wants his phone back and doesn’t appreciate Poppy reading his messages and wading into his personal life.
What ensues is a hilarious and unpredictable turn of events as Poppy and Sam increasingly upend each other’s lives through emails and text messages. As Poppy juggles wedding preparations, mysterious phone calls, and hiding her left hand from Magnus and his parents . . . she soon realizes that she is in for the biggest surprise of her life.
The Perfect Match by Kristan Higgins
What if the perfect match is a perfect surprise?
Honor Holland has just been unceremoniously rejected by her lifelong crush. And now — a mere three weeks later — Mr. Perfect is engaged to her best friend. But resilient, reliable Honor is going to pick herself up, dust herself off and get back out there…or she would if dating in Manningsport, New York, population 715, wasn't easier said than done.
Charming, handsome British professor Tom Barlow just wants to do right by his unofficial stepson, Charlie, but his visa is about to expire. Now Tom must either get a green card or leave the States — and leave Charlie behind.
In a moment of impulsiveness, Honor agrees to help Tom with a marriage of convenience — and make her ex jealous in the process. But juggling a fiancĂ©, hiding out from her former best friend and managing her job at the family vineyard isn't easy. And as sparks start to fly between Honor and Tom, they might discover that their pretend relationship is far too perfect to be anything but true love…
