After all the human woman have been mated who is left to read about in this series? We return to a sa-khui couple that broke up after their daughter died shortly after her birth. Asha and Hemalo had resonated but they weren't a love match (at least on Asha's side). Then after their baby died, Asha's heartbreak was so great that Hemalo moved out thinking that she wanted to be alone. She saw this as being abandoned.
Afterwards, while still processing her grief, the earth women show up and all of a sudden there are babies everywhere - adding to her depression. Every new kit reminds her of what she lost. While Hemalo seems to be doing well he is grieving too - he not only lost a child but his wife.
When Claire befriends Asha it helps give her a purpose and surprisingly, she and Hemalo resonate again. After the last pregnancy, Asha is afraid. The two find themselves out in a cave, alone and need to work out their issues to let their love overcome their fears.
This is a great change from the previous human/sa-khui relationships and we get to see a different side of several characters.
