Last Resort, On One Condition, and Final Proposal — the three S.I.N. books, all published in 2022 — share a premise around negotiated agreements between people who have too much at stake to be honest about their feelings. K. Bromberg uses the contract or arrangement framework common in contemporary romance to set up the tension her heroes and heroines then have to work through.

The three books can be read independently but share a connected world and some recurring characters.
