Sci Fi Romance Books: Find Your Next Read
Sci fi romance books on one free shelf. Filter by trope, heat comfort, and aliens or humans only. It filters rather than ranks, so it is not for you if you want a top ten.
- Pick a trope, a heat level, and whether you want aliens.
- The list updates the moment you choose.
- Open any book for its details, then save it to your shelf.
One way to test our own entry costs nothing: the first three chapters, free and without an email address.
Sourced sci fi romance books; we publish The Starfall Accord, marked Ours, and it uses the same filters as the rest.
It has no reader reviews yet because it has not launched, so the free opening chapters are the fairest test.

This shelf is science fiction romance only.
For closed door books outside it, the shelf where nothing explicit is on the page covers seven genres, and a shelf built from the mood you are in starts from a mood instead of a filter.

Frequently asked questions
Where do the book details come from?
Some entries are sourced from publicly available publisher, author, or retailer listings, and each one says which.
Publishers rarely state a door label at all, so where we give a heat level and no listing does, it is our editorial estimate and is labelled as one.
Where a heat level is not stated anywhere, the book is marked accordingly.
None of it comes from our own reading.
Is my saved reading list private?
Yes.
Books you save go to a private to be read shelf stored on your own device.
There is no account and no sign in required to use the picker or to save books.
Is The Starfall Accord included in the picker?
Yes.
The Starfall Accord is included and marked Ours because we publish it.
It uses the same trope, heat, and aliens filters as every other book, so it only appears when it matches what you picked.
