It's My Party — Cindy Blake

For as long as she can remember, Isabel has been consumed with love for David, a man who is now her business partner and married to another. Together they run PARTYTIME, organising celebrity parties and until now, they've been doing very nicely. Until, Stryker McCabe, a brash American with big ideas, decides to set up a rival company and steal their biggest clients. David is furious; so Isabel decides to get her revenge by taking him on at the seedy casino she knows he visits. Trouble is, Stryker is falling for Isabel, David still isn't interested in Isabel, and David's brother, Peter, has fallen in love with Stryker. Confused? You're not the only one but by the end of this wonderfully romantic feel good novel everyone has found their rightful place.
