I've Got Your Number by Sophie Kinsella

Synopsis :

I’ve lost it. :( The only thing in the world I wasn’t supposed to lose. My engagement ring. It’s been in Magnus’s family for three generations. And now the very same day his parents are coming, I’ve lost it. The very same day! Do not hyperventilate, Poppy. Stay positive :) !!

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.

I can never resist a title of Sophie Kinsella.  The last book read wasn't that good but am glad that tides are turning with I've Got Your Number. 

I've Got Your Number is an independent title and readers are first introduced to Poppy Wyatt as she frantically tried to find her missing engagement ring.  She found a phone instead and decided to make it her own so that the hotel can contact her when they found her ring.

The thing is, the phone belongs the the PA of Sam Roxton and he wanted it back but Poppy isn't letting go of it as it's her connecting in finding her precious engagement ring.  What follows can then only exist in the world of Sophie Kinsella which are both funny and bittersweet at the same time.

To me, at least Sophie Kinsella proved that she still got her number.  Right after The Wedding Night, I thought she has lost it.  Glad to have you around still, Sophie!
