Half is missing

Blade and Rex quickly realize that being together is insufficient. They are trying to be separated from the outside world, including Nick, Blade's former partner, who doesn't want to go home alone and humiliated. Blade and Rex are aware that Optimo's silence does not bode well for them or their packs, even though they have yet to learn what he plans to do in the north. Also, a new threat comes from the east. It gives Blade and Rex a deadline and forces her to go back to her old life, which she must now continue without her family or her grandfather's help.
