Storyverse and the Time Ghosts Curse. STORYVERSE, #2

Tessa isn't sure how she'll fit in at Sea Angel Academy. The historic school is more interested in the prestige of its graduates than their magical talents, but at least she'll be reunited with her friends and safe from the minions of Abigail searching for the Ring of Everything. It doesn't take long before the year surprises her: there's a time-ghost attacking the Academy's students, Abigail's followers are searching the school for the would-be Tyrant's heir, and the ancient and wise Clock Lord will adjudicate the end-of-year tournament for the first time in a century.
It promises to be a hectic year, and that's before the ship hosting Sea Angel Academy is taken over by an arcane gang, forcing Tessa and her friends into hiding. With the fate of the Academy-and the Storyverse itself-resting in the hands of Tessa and her friends, they'll need to make some unexpected allies and face uncomfortable truths in order to retake the Academy and graduate the school year.
