With Aspen and Chance on a road trip to find her missing father, Maylander sends his Tigersharks through the hydroport to infiltrate the Capital City of the Blue. With the city still reeling from the destruction of Saba, the Tigersharks should have little resistance...but no one told that to Kiani! It's an underwater slugfest as Kiani, Siphon and Brande take on the 'sharks, and the outcome of the battle will leave you breathless! Brought to you by the creative team of J. T. Krul, Koi Turnbull and Jason Gorder, presented with an all-new cover by series artist Koi Turnbull!
