In summary I imagined book 2 having a guy named Khai whose wife was driven to suicide by her link thanks to Benna's freedom towards linkers So he blames her. Khai break into the health facility with Dr Frenchwood's research and turns himself into a linker but a very powerful spider. Benna couldn't link to Corin so married Jesse and they had a daughter who can link to any mind even if it belongs to an animal. Khai knows about her and demands her powers be stripped, Benna refuse and to demonstrate his power, Khai screams into people's minds until they bleed from nose and ears to death. The people panic, the linkers won't go back into hiding hence civil war. Khai kidnaps Benna's daughter and to save her Benna has to become a linker again with Corin's help using Dr Frenchwood's work.....
