Wow another breath taking adventure story where our amazing superhero and her allies do their best to save the world they are now in. Ulka had lost all her memories in the last attack, but once she starts to remember who she really is, she is hell bent on continuing her job of saving the world. Ulka is a fantastic sigma 5 superhero, she is one of a kind, and her powers are insurmountable but her foe is very dangerous, he is known as DN and he is a serpent-man. Though DN uses his people through terror which he instils in them, he still answers to another higher up in the power chain, and he fears the one in command as much as his subordinates fear him. Rakra is the master behind DN, and he calls the shots aiming to use the sigma, so his people would come in as saviours and get accepted as friends, thus winning the planet without a war, or at least that was the plan, but he was not taking the sigmas seriously enough. When Ulka, Ruby, Teeva and Yagni got together they were a force to be reckoned with, and though they faced great dangers and had their lives on the line many a time they managed to defeat enemies such as Bua, Mohita, Narbali, Horez and others who kept coming from other universes across the parallel multiverse. There were many betrayals and great battle scenes but damn that ending! What a cliffhanger, after all the action this ending is so cruel on poor Ulka and on us the readers, and I cannot wait for book 3 in this amazing superhero sci-fi series.
