A little Help Please

I am having a senior moment trying to remember a story. I have been reading dragons stories recently. I read a story in the past, that was similar but different. A young boy was at a ceremony where young girls would join with( I believe its a joining of some sort). The boy sees some major figure show up and he tries to get a closer look and falls in the pit or pushed, with those egg sorts. He lands next to a black one which encompasses him. He is strong and fights and she actually joins with it. I feel like they were some type of winged beings.

I know not much help on my memory. But some of you remember everything and might make sense of my babble. I tried but thanks...
