I feel like the title of the 5th book here really gives the game away, in terms of where these books are going.
The Nardone Family Saga, this has grandiosely styled itself.
Without editing, here are my thumbnail notes from The Book Journal:
Well, this was fun. Stupid fun, but fun.
In the first book, which I thought I had read but had not in fact read, we buy a chick at auction to prove ourselves to the Evil Dudes ™ we are trying to bring down. In the second and third, we bring people down (yay!), fall in love with a cop, turn out to be the brains in the family while simultaneously being a woman (gasp!), and kidnap the love of our lives.
There are a couple of pregnancies.
Everyone goes legit, and they all live happily ever after.
This review feels like a bit of a cheat, sorry.
