The Weird Problem of Good

Romance isn't always a garden of delights. Sometimes it's a no-holds-barred battle to the death with the incarnation of evil. Prem's wedding to Nasreen collapses when she uncharacteristically bows to her conscience and walks out of the ceremony. He wanders alone to the town centre where he bumps into Ursula, a gypsy refugee from Eastern Europe who manages to convince him she's someone she's not. Warming to her, despite his ordeal, and dimly sensing her predicament, he invites her to stay with him on a friends-only basis.
She accepts. Fast forward a few months. The lives of all three have now become inextricably intertwined, with mutual forgiveness and a hastily agreed unity of purpose their only practical options. Through a series of misadventures, they've found themselves confronting a network of women-traffickers who'll stop at nothing to protect their interests and expand their empire. If that means torturing Prem to death, and introducing Ursula and Nasreen into 21st century sex-slavery, so be it.
How did they get from one (fairly run-of-the-mill) state of affairs to the (off-the-wall and utterly terrifying) other?And just what is the 'weird problem of good' anyway?Don't ask me. I'm just a blurb. You'll have to read the book.
