Symbiotech - C. E. Clayton - Bog

Ellinor is done-running and hiding.
Cosmin has made it violently clear that wherever Ellinor and Kai go, he will find them. And, he will gladly make their families suffer until Ellinor returns what she stole from him. But Ellinor cannot, and will not relinquish Fiss; not to those who would bind and shackle him to serve their greedy agenda, not to anyone.
Even with her magic returned, and with Fiss, Kai, and Jelani to help, they are still no match for Cosmin, a point made agonizingly clear when Ellinor and her friends tangle with an old foe. Without more power, Ellinor has little hope of saving her family before there is nothing left to save. The power is there, but learning how to harness her upgraded magic is complicated, and time has run out. Then there are other distractions, in the guise of feelings Ellinor would never have thought possible for her again, if it weren't for the charming Jelani and her growing attachment to him.
Allies are in short supply, and any help will come with a price, but that won't stop Ellinor from returning to Euria. She will face Cosmin von Brandt and save her family, or die trying.
