Silvergates: Navigator (Book 2 complete)

Five years ago, the first Silvergate was found. At first, they called it a hoax. But since then, more and more people have entered the alternate dimension called Northworld, received their Interface, and going on to real adventures. As it gained momentum, they called it a problem. Now, they call it a crime. But for nearly half a million people, it's now their real home. Yearning. Escape. Duty. The reasons to go are many. Despite the criminalization of Silvergating, people still seek out their ticket to Northworld. But for new Gaters Jasper Hill, Erika Haglund, and Henry Esteban, Northworld has surprises in store. Not every rumor is false, not every conspiracy theory is stupid. When the veil lifts for them, showing truths about Northworld that no one suspected, they may have difficulty making themselves heard. And being trusted may mean the difference between life or exile forever. Northworld is a litrpg story where people enter an actual world, submit to an RPG-type Interface, and discover an alternate reality. You could describe it as a reversible Isekai since people alternate between Earth and Northworld. The characters are usually casual about it, which means informal talk and infrequent profanity. Four-letter words dropped in conversation (or internal monologue). Warning: one potentially horrible theme and one implied sex scene. Book 1 and 2 are complete, as the title says. Book 3 is scheduled for a fall start.
