The crimson fortress

Four siblings. Two enemy territories. One long buried secret. Without magic to protect Ashoka's borders, time is running out. The whole country is at risk from enemy territory closing in. As their quest forces the siblings to split up in search of answers, they will uncover much more than an evil emperor's schemes. And when an ancient power is released, Vira, Riya, Ronak and Kaleb will need to come together yet again to face the past and save their futures once and for all.
