Callum: Past & Present by KM Lowe

When your past and present collides it wreaks havoc with your emotions and spins your world out of control.
For Callum, being a Guardian Shifter, life is never dull. Life in general is full of surprises; always something crops up unannounced.
However, finding his soulmate opens old wounds and leaves many questions unanswered. Many questions he probably should leave unanswered, but the shifter in him leaves no stone unturned, which in turn, opens the portal to hell.
The Guardian Shifters have yet another battle on their hands, but will their unity and strength grant them a happy ever after?
