Yooooo, it's a pre-Plum Janet Evanovich!  It's got capers and slapstick and... business!  Ivan is a schooner captain.  Stephanie is an ex-cop, now cute bread and breakfast owner!  Tess is maybe a ghost!  It's got no major trigger warnings beyond what you'd expect for this sort of madcap comedy business - gggggghosts, cold-ass Maine water, possibly a lie about a shower?, a whole ass town gaslighting this poor woman, bad cooking!  I don't want to give anything away but if you're okay with "screwball" including that gaslighting business this is harmless.
