So I really enjoyed Collusion and thought it was a great addition to the series. The two books do follow one another pretty closely, and although I think you can understand this plot without reading the first, you will miss a lot of Bo and Lucky’s back story that really lends gravity to their relationship. So I would definitely recommend starting with Diversion (especially because it is excellent) and then picking this one up. It is a really great book in a really enjoyable series and I definitely recommend it.
