A Lion and His Cub

Fifth Year: Harry fathers a child with Grace, a muggle girl he believed was his soul mate. Now she's gone and he's left to raise the babe on his own. However, Dumbledore, Mrs. Weasley and a few others don't believe that the baby is Harry's, but a plant sent by Lord Voldemort. Who is right, Dumbledore or Harry, and will they be able to deal and accept the truth? Occasional OOC.
