<p> Lizzie Nichols is back, pounding the New York City pavement and looking for a job, a place to live, and her proper place in the universe (not necessarily in that order). </p> <p> "Summer Fling" Luke's use of the "L" (Living Together) word has her happily abandoning plans to share a one-room walk-up with best friend Shari in exchange for cohabitation with the love of her life in his mom's ritzy Fifth Avenue <i>pied-&#224;-terre</i>. Lizzie's landed a non-paying gig in her chosen field&#8212;vintage wedding gown rehab&#8212;and a paying one as a receptionist at Shari's boyfriend's father's posh law firm. So life is good . . . for the moment. </p> <p> But almost immediately her notoriously big mouth is getting her into trouble. At work she's becoming too chummy with society bride-to-be Jill Higgins, inflaming the ire of Jill's troublesome future mother-in-law. At home she's made the grievous error of bringing up the "M" (Marriage) word to commitment-shy Luke. Once again joblessness and homelessness are looming large for hapless blabbermouth Liz&#8212;unless she can figure out some way to babble her way to a happily ever after. </p>
