Summer Donahue is not Ben Martin's type of woman. Ben is conservative, thoughtful and the model of self-control. Summer is whimsical, spontaneous and just a bit flaky. So why, when she breezed into his office like a tropical storm, was he so instantly and inexplicably attracted to her?

Summer consulted Ben to have her business's taxes done. But when it comes to light that Summer's ex-husband and ex-accountant Malcolm has embezzled most of her liquid assets and put her on the brink of bankruptcy, Ben throws aside all of his iron-clad rules about getting personally involved with his clients. Summer and Ben go to Mexico to find her ex and save her business. But in the process Ben loses more to Summer than his personal credo — he loses his heart as well.
