In DAR & Earth: Evolution, the final installment of the DAR & Earth series, Aelish finds herself held captive by King Cardissius in the Kingdom of Yasteron. While imprisoned, she uncovers things she could never have known otherwise about the king and the kingdom itself. But can she survive the unimaginable conditions of her imprisonment to effect any meaningful changes in Yasteron? Meanwhile, DAR is severely polarized. Earth born Head Council Members want to directly retaliate against Yasteron for abducting Aelish on a peace mission. Yet other Council Members and the Council Chair wish to adhere to DAR’s Oath of Peace. Komprathia, however, begins a war against Yasteron as Aelish is the Living Legend who freed their kingdom from tyranny, centuries ago. Komprathia’s actions have the potential to draw the Alliance of Magical Dominions into a worldwide magical war against Yasteron. Accepting that DAR will not initiate a rescue of Aelish, Thagar requests permission from the Council Chair to develop a covert mission to try and save her. The Council Chair grants his request, but he’s faced with the fact that no being has ever entered Yasteron undetected. Isabela has stepped back from her work and is undergoing mental health treatment in a psychiatric facility. But when she discovers what’s happened to Aelish, she experiences a psychotic break. Andrew Devereux, her partner on the LECCS vaccine, finally convinces her to accompany him on a worldwide tour to promote the vaccine. Vaccination rates remain abysmally low and time is running out. The overall global temperature is very close to flipping the switch on the deadly climate syndrome, poised to extinct humanity. Worlds apart and still estranged, can Aelish and Isabela find a way to save humanity from the climate crisis, as well as find a way back to each other?
