Ryuvian's manga / #fantasy(4)

Summary: 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. For that he's going to need training, allies, and a lot of ingenuity. The journey won't be easy, but Corin won't stop until he gets his brother back. ***I read this book before it ever became a webtoon and it's pretty good. It's mostly kid-friendly, lots of action, and no romance until way later and then it's not very heavy only a part of the moving plot. Lots of interesting characters and mystery
