Nick survived a 7-foot-tall, black cloaked, evil clock and its host of bloodthirsty minions. Trevor, Wren, and their friends survived the puzzle box from Hell and the horrors it spewed out in a night of terror at their exclusive boys school. Jax managed to not get eaten by the ravenous Kraken out for Campbell blood while also rescuing his long-lost cousin, Marnie. The Campbell cousins and their friends made it back to Campbell Island despite a harrowing flight over the Atlantic and a crazed Gremlin trying to rip the plane apart all around them. Marnie getting sick combined with Wren's new Brownie abilities caused them to get stuck inside Marnie's dollhouse with Marnie's imaginary friend desperately trying to reconnect with her after ten years alone and forgotten. Christmas and Solstice should have been blessedly relaxed, but Trolls, Ogres, and a particular Demonfae made sure that didn't happen. Finally, the Campbells have had a few quiet months to study and grow without any attacks or threats of any kind. Sara, Olivia, and Selena Campbell are all about to deliver five new Campbells to the mix, and everything seems to be going well, despite Selena's pregnancy being high risk because Sirens don't have twins and survive. Mera and Luna are in the Mediterranean studying how to be full-fledged Sirens with their cousins, when Mera and Princess Beatrice are kidnapped by King Konstantin of the Balearic Sea Kingdom, his brother, Prince Rurik, and their mother, Queen Elessa, for leverage. They aren't satisfied with having reclaimed their home. They want Marnie and Princess Naomi to forfeit themselves to be their new brides, and for Naomi to hand over the Ligurian Sea Kingdom. And the Campbells' good friend, Ahmed, is really a devious Jinni looking to kidnap the baby Campbells when they are born because there are some in the world of magic who would pay a great deal to own a Campbell infant or set of twins. As Trevor lays it out for his cousins and friends as they discuss their options: “OK, let’s get serious,” Trevor said, feeling a bit better from the banter. “We have two little Mermaids to rescue, two Sea Kingdoms to outsmart, three pregnant women about to give birth, and now a Jinn not to let onto our knowing what he is while we figure out what he’s doing and how to get rid of him. Oh, and possibly a closer look at Chad’s new Gremlin friend so we can assure ourselves he isn’t going to murder us in our sleep while everything else is going on. Have I left anything out?” Get ready. It's going to be a bumpy ride!
