Getting rid of Aunt Edna Book

This is the second Maxted book I've read and I'm seeing a pattern - or is it a formula? Selfish, self-absorbed, shallow working girl from a very dysfunctional family tries to sort out her love life, stumbling through several inappropriate relationships and alienating "her true love" until he sees through her snarky exterior to the potential within and they go off happily ever after. Hmmmph. It was ok for the first book. But to repeat the formula is like eating leftovers, not as good the second time. And yet, the book does somehow draw you in. Not sure why. I certainly would never want to be friends with either main character in the Maxted books I've read thus far - they're mean, spiteful and seemingly incapable of treating people well. It's hard to enjoy a book when the characters are so unlovable. So, I'm torn. The book is funny in places, and Maxted can certainly turn a phrase. But do I want to try another of her books, on the off chance that the plot will be different? Stay tuned...
