I recommend novels where the female protagonist is 10 years older than the male protagonist.

One common theme is adventure. Koga is often depicted as a strong and brave character, so stories might involve him taking the reader on exciting adventures in his world. Another theme is friendship - turning - into - love. They start as friends, get to know each other better, and then develop romantic feelings. Also, there could be a theme of cultural exchange, as Koga may have a different cultural background, and the story could explore how the reader and he learn from each other's cultures.

For the PJO side, Nico di Angelo could be a great character. His control over the dead could have some really strange and interesting interactions in Skyrim, where there are also undead creatures. On the Skyrim side, Ulfric Stormcloak or Elisif the Fair could be included. Elisif's leadership and Ulfric's military might could be factors when dealing with the demigods. If the demigods get involved in the civil war in Skyrim, their powers could completely change the balance of power. And Luke Castellan from PJO could also be an interesting character to bring in, as his complex personality could add a lot of drama to the crossover story.

One plot idea could be that Percy's singing has magical properties. Maybe it can heal the wounded or calm the angry sea gods. So, he has to use his singing to save the day during a big crisis in the demigod world.

Another great one is 'Rebecca' by Daphne du Maurier. It's a classic thriller that creates an atmosphere of unease and mystery from the very beginning. The unnamed protagonist is haunted by the memory of her husband's first wife, Rebecca.

I don't have enough information about the dog Lulu's true story. It could be a story of Lulu's loyalty. Maybe she waited for her owner at the same spot every day for years, no matter what the weather was like.

Peck in Animal Jam is an interesting character. She's often involved in various adventures in Jamaa. For example, she helps other animals with tasks like finding lost items or solving simple mysteries. She's known for her kind heart and her ability to get along with different species.

One of the main themes could be self - discovery. After transformation, the characters might have to re - evaluate who they are. Another theme might be relationship changes, as the transformation could affect how Mine and the other character interact with each other.

I'm not sure specifically as I haven't read it. It could be about the different images or personas that a character or characters have in the story.

The main character is obviously Chicken Little. There are also other animals like Henny Penny, Ducky Lucky, Goosey Loosey and Turkey Lurkey who get involved in Chicken Little's false claim that the sky is falling.

I don't know the 'acacia christmas story' well enough to list its key elements. But it might include the acacia tree itself, Christmas traditions, and perhaps characters associated with the story.
