Rex Aftermath. Elei's Chronicles, #4

There is war on the Seven Islands. Elei and his friends have unlocked the weapons held underground, but the Gultur regime is not so easily put down. Mantis and his ragtag army of kids need all the help they can get. Elei, Kalaes and Alendra return to Artemisia to create a diversion, while Hera, Sacmis and Mantis attack Dakru City, in a final attempt to bring peace. But with a net of betrayal closing around them and Rex set against Regina in a final confrontation, the price might prove too heavy.
