Summary
Agent Three is done. He’s quitting the Splatoon. He’s not going to keep dealing with Craig Cuttlefish not respecting him as a person, even if he’s not sure where to go next.
A mysterious entity known only as the Kamabo Corporation has been spiriting away Octarians ever since DJ Octavio battled Agent Three. Now that the DJ has returned to the Domes, he’s going to figure out what’s going on and get those octolings back.
But Octavio is going to need someone strong. Someone fearless. Someone who won’t falter when rushing head-on into a trap. Someone like Agent Three…

Summary
Do I look like the kind of person who writes a summary? Those are for the people who wanna ruin the book before they even read it. Might as well just print the book back here, huh?
ACTUAL SUMMARY: A week after her defeat at the hands of Agent 4, Coral Kurayami, the newly appointed Major General of the Octarian army, and her older brother Mark set off to Lemuria Cape. Their plan: kidnap Cap’n Cuttlefish and Agent 3 and trade them as prisoners of war for their captured leader, DJ Octavio. But things take a turn for the worse when, during a battle with Cuttlefish and Three, all four are sent into a chasm created by an earthquake.
Waking up in a strange subway system deep below the surface, Coral and Mark reluctantly team up with the scourge of their race, namely Cuttlefish, to try to find Agent 3 and get out of the subway. Along the way, they’ll confront former friends, hordes of zombie-like Octarians, a ton of evil robots, a deadly assassin, and... a weird pay phone who offers them a way out.
Rated Teens only for some dark content.

Summary
Sometimes things don’t work out how you want them to. And that’s okay! As long as you keep trying.
Applicant 5059 had grown cold. Her days of trying long gone. The sound of radio static was all she heard.
Until she met him. A small child that had no place in the Deepsea Metro.
When they met, she knew that no matter what happened, she had to get him out of that place, to do anything in her power to make sure his fate was not the same as hers. Even if it took everything.
Join 59 and Ocho over this long journey though the trials of fighting, puzzles, and even comprehending some long forgotten memories. Watch the relationship of a brainwashed solider and a distraught test subject develop with moments that might make you laugh, or cry.
(This takes place in the Deepsea Metro BEFORE Splatoon 2: Octo Expansion)

Summary
Marina, Pearl and Eight were definitely not expecting to end up falling down below while on Mount Nantai, nor were they expecting to find weird colored octolings and a talking telephone. I guess there's nothing to do but go onwards?
..
Marie wishes finding her cousin would be easy... And it is... She's there and telling them to go away, no Octavio in sight. What's this about missing, unaccounted for Octolings that weren't found on the surface?
..
Both Octavio and Craig wake up in a lab deep underground, both of them noticeably younger. Traversing through the halls they find nothing but bright, weirdly colored ink and abandoned office spaces. Yearning for a way out they continue onwards.Series

Summary
Summery from SquidgeWorld:
"After waking up in an old subway station Agent 8 and Cap'n Cuttlefish search for an exit, coming across an old telephone that says it will lead them to the 'Promise Land.'
Well what The Telephone wasn't expecting was Agent 8 carrying a Splattershot they've smuggled past the tutorial section after finding the key to get here. How will this change things, if any?"
