My Ex Is Dead, I Need to Burn Paper If I Have Something to Do

My ex-boyfriend died. Died in a B&B. The first suspect at the crime scene was the owner of the B&B. That is a nagging mental illness, and he actually robbed me of the only relic left by my ex-boyfriend! Wait, something's wrong! We have opened a door to another world! The whole book is a unit story, including solving crimes, adventures, revelations, and the male protagonist (falling in love). It is very healing, relaxing, and emotionally stable.
