Five years ago, Corin Cadence’s brother entered the Serpent Spire — a colossal tower with ever-shifting rooms, traps, and monsters. Those who survive the spire’s trials return home with an attunement: a mark granting the bearer magical powers. According to legend, those few who reach the top of the tower will be granted a boon by the spire’s goddess.He never returned.Now, it’s Corin’s turn. He’s headed to the top floor, on a mission to meet the goddess.If he can survive the trials, Corin will earn an attunement, but that won’t be sufficient to survive the dangers on the upper levels.

Zorian Kazinski has all the time in the world to get stronger, and he plans on taking full advantage of it.

A teenage mage of humble birth and slightly above-average skill, Zorian is attending his third year of education at Cyoria's magical academy. A driven and quiet young man, he is consumed by a desire to ensure his own future and free himself of the influence of his family, resenting the Kazinskis for favoring his brothers over him. Consequently, Zorian has no time for pointless distractions, much less other people's problems.

He does have to unravel it, too, because the loop clearly wasn’t made for his sake, and in a world of magic even a time traveler isn't safe from those who wish him ill.

Fortunately for Zorian, repetition is the mother of learning…
