i guess this dragon who lost her egg

She is found by a kind - hearted ranger who takes her back to her family.

Thank you for providing this plot for me to guess an idiom: Money is not as good as material goods. This idiom means that it is better to have something than to spend money on it. In the plot of the novel, a person used money to buy an egg, but what hatched was a chicken. This meant that money could not replace the true value of an item.

Sorry, I'm not familiar with this novel, so I can't tell you who the author is. It could be a relatively unknown author or a new release that hasn't gained much widespread attention yet. You might need to do some research in literary resources or online book communities to find out.

I don't know as I haven't read it. Maybe there's a brave hero.

The main character is definitely the entity that is reborn as a dragon egg. This character experiences a complete transformation from its previous form (although we may not know what that was initially) into a dragon. Along the way, there could be other characters such as wise old dragons that act as mentors, or perhaps some humans or elves that cross paths with the newly hatched dragon. These secondary characters can either be friends who help the dragon understand the world better or enemies who see the dragon as a threat to their own existence or power.

The protagonist is usually a central figure, often a person with a kind heart and some sort of special ability or destiny. Then there are the harem members, which can include female warriors, mages, or even characters from different races. There is also often a wise old mentor figure who gives advice on how to take care of the dragon egg.

Well, in this short story, perhaps the main character is a simple farmer who accidentally finds the dragon egg in his field. There could also be a group of villagers who are initially afraid of the egg but later come to support the farmer in protecting it. And then there could be a dark sorcerer who hears about the egg and tries to use it for his own evil plans, making him a key antagonist in the story.

The main characters are the boy and the dragon that hatches from the egg.

The dragon itself, of course. Starting from the egg stage, its journey of growth and development makes it a very interesting character. There are also probably some magical creatures that interact with the dragon. Maybe a wise old owl or a mischievous fairy that cross paths with the dragon at some point.

You could try looking in local bookstores. They often have a section dedicated to fantasy novels where the 'dragon egg novel' might be located.
