Love Bomb by Lisa Zeidner

When a wedding-dress-wearing, shotgun-toting woman hijacks Tess Nathanson's nuptials, the mood quickly veers from happiness to surprise. Is she part of the unusual ceremony? Toss in a bomb threat, a SWAT team — and the icing on the cake — a room full of dysfunctional family members (including multiple Jewish psychiatrists), and you have a comedy of manners that truly puts love and understanding to the test.

Love Bomb, Lisa Zeidner, $29.
