1 trouble-causing time traveller, 2 future time lines and 3 types of portals helping the 6 main characters prevent a war.
This is the 4th novella in the series Portae inter nos.
Throughout this series of novellas, six characters develop their powers and their relationships with friends, with siblings and with romantic and sexual partners.
They travel through time and to alternate dimensions both by accident due to a lack of control over their powers and intentionally due to being summoned to help save their world or a time line.
General information:
light themes;
(hopefully) fairly easy to read even if English isn't your main language;
sex is mostly implied. Slight descriptions of actions that wouldn't be considered sex themselves are added a couple of times to clear up what is and isn't happening.
There are 2 versions: mostly women main characters and mostly men main characters. For the mostly men one, you'll need to go on my site (which Kobo doesn't let me put here but should be found in the sample fo the book). The story is the same. It's to offer a choice to people who have a preference between those 2 genders.
