A brilliant sequel to Falling Kingdoms. 
 In Rebel Spring, we find Cleo being held as a prisoner of war. I enjoyed Cleo's character development from a frivolous and spoiled princess to a scheming and cunning prisoner. I look forward to where her character is headed in the story. 
 Jonas is now a rebel leader, seemingly doomed for failure. Will he achieve his quest for revenge and justice? 
 Magnus is such an enigma. He is so dark, so twisted, but deep down he has a good heart. Oh god I ship Magnus and Cleo so hard. 
 Lucia is in a coma after the attack on Auranus, but we still see her POV in this book. I won't give any spoilers, but some interesting insights are revealed. 
 We also gain some new POV in this book. Some interesting new characters are introduced, who only enhance the story. 
 We still have main character deaths in this book, but I honestly love the shock and surprise when this happens! No one is safe. 
 Also alliances are constantly shifting. Once enemies are now (reluctant) allies. 
 I am loving this series! Definitely has made it to my coveted 'must own real book in case of zombie apocalypse list'. 
 On to Gathering Darkness!!
