In Our Bloodstream.

The battle is over, clans win, scourge is dead. Bloodclan is no more, right!?

WRONG!
Scourges mate, Phoenix, a golden tabby, is heavily pregnant with his kits. She plans revenge on firestar and sneaks into the clans as a "loner", soon finding herself in labour. With three young kits to raise she stays in Thunderclan clan and the kits learn about their gene pool...

SHADOW:
The first born of the three, as the oldest he is the darkest in heart and fur, a splitting image of his farther, all except all his paws are white.
Growing to be the cat of the plot he struggles with his true emotions..

BLAZE:
The second born, he's gold like his mother and disapproves his father's ways and takes interest in the clans lifestyle, rejecting his mother and shadow.

SILVER:
Third times the charm!, especially in her case the only girl in her litter and silver like the stars, cinderpelt interprets she has power, power of a medicine cat.
Apprenticed into the med den she finds she reads stars like magic!
