Frankie Rowley is far too practical to believe in karma or fate ...and her family and friends reckon that work-obsessed Frankie's strongest relationship is with her phone. (And why not? At least it never judges her for cancelling dinner for the umpteenth time.) When she loses that precious phone on a business trip to San Francisco, Frankie is forced to hire a replacement. Soon she's getting texts meant for someone else - a woman called Aimee who seems like a lot of fun, and whose family clearly loves to keep in touch - and whose presence in her life is the last thing Frankie needs. Frankie goes on the warpath, but she is in for some surprises when she blunders into Aimee's world. And the biggest surprise of all is how your life can be changed forever by losing a phone. Frankie may not believe in karma or fate, but suddenly it looks like they've got her number ..
