Secret Twins For The Alpha

Elena, heir to the Silver Moon Pack, is robbed of her succession when her father seizes power. To meet her grandfather's will, which requires her to bear an heir first, she ends up in a one-night entanglement with Arthur, Alpha of the Obsidian Pack, and gives birth to twins, one of whom is stolen at birth. Five years later she returns with her other son, unaware that the missing child is being raised by Arthur, and neither knows the other is the twins'parent.
