When it comes to falling in love, Tammy Whinot will stop at nothing:No matter that when she meets Mr. Perfect, he's shooting it out with a Chechen convenience store owner.Or that five minutes later he takes a leap over a drunken Porsche into a coma and a stint in a wheelchair.Or that the fixer-upper Tammy buys Mr. Perfect contains a family of ghosts trapped in an afterlife of murky tribulation.Or that tribulato numero uno is the mobster Tony Ten Finger's obsession with recouping the $9.5 million Ghost Ted embezzled from him.What a girl needs in this dating hell we live in are great instincts, and Tammy has some of the greatest:She can see past Joe Lamb's haphazard suicidal tendencies to the pot of dull stability that lies beneath.She can charm a family of irritated ghosts into defending her to the — uh — death against a swarm of gangsters.She can spot the rose in a patch of weeds, the courage in a frightened coward, the hope in a broken bicycle, and the love in a mistreated child.If the finest quality of an American hero is an absolute faith in humanity, then Tammy makes the grade with powers to spare.Don't misunderstand her — sooner or later everybody does something bad — Tammy herself isn't above a little kidnapping, blackmail, and grand larceny — but the trick in love and life is to find someone who does bad things badly and ugly things worst of all.
