362L: Sister Turns Out to be Another Personality

I’m looking for a YA book from the late 80’s or early 90’s. It’s about a group of school students that go to an old house. The main character is a girl that has a sister. It’s revealed later that the sister is actually another personality.  I think there was a picture of a girl looking in the mirror on the cover. I think some bad things happen to the other students, but I don’t remember specifics.

362K: Mysterious Buckle Leads to School Bus Crash

I am looking for a YA book about a girl that has a horse with a mysterious silver buckle or medal that she puts on her horse. When she touches the buckle, she can make a wish. One of the wishes she makes causes a school bus crash. The buckle is linked somehow to a dark force that ends up appearing at the end of the book. It’s a pretty dark book. I’m thinking late 1980’s or very early 1990’s.

361K: Four Girls at the Beach

Looking for a book about 4 girls spending summer at beach, they each have different color tote bags, one swims in the sound and I think almost drowns, one bakes muffins with granulated sugar on top. I think it was published between 2000-2010, it’s a middle school/YA book with chapters.
 
I have tried to find it everywhere. It’s not a Sarah Dessen novel, but I’m pretty sure the author is a woman. I want to say it’s between 150-200 pages, but I could be off. It’s been a while since I read it. I really appreciate your all’s help!

361G: YA historical novel heroine Margaret Plantagenet of York, later Margaret Pole

Young Adult historical novel about the childhood/teenage years of Margaret Plantagenet of York, who later became Margaret Pole, and her brother Ned (Edward, Duke of Warwick), at the end of the War of the Roses and beginning of the Tudor period.  It starts in the court of her uncle, Edward IV, after her father (George, Duke of Clarence) has been executed for treason, and ends with her brother’s execution and her romance with Reginald Pole.  My memory is that the heroine is known as Meggy or Peggy. I probably read this in the early 60s, but it might have been written in the 30s, 40s or 50s. I thought the author might be Elizabeth Janet Gray, Rosemary Sutcliffe, Margaret C. Leighton, or Elizabeth George Speare but can’t find anything that seems to match this story among their titles.

361F: Was Magical Prudence Really There At All?

Looking for a young adult book involving a skinny girl with long dark hair named Prudence who is possibly befriended by main girl character. At first I thought they were sisters but not sure. She might have mysteriously moved in to empty town haunted house. Don’t remember her having mother or if did was absent or witch. Remember big hill and snow with kids being out of school – Prudence might have made it magically snow to get them as friends/stop picking on her. Then think she just up and left one day and it was wondered if she was actually ever there at all. Don’t know if she was school aged/ever went to school

361E: Boy lives in lighthouse, has AI companion, fights elemental monsters

This is a children’s series
Boy lives in lighthouse with an AI companion who designs all-terrain ships/vehicles. Boy uses advanced technology mods to fight elemental monsters. There was a secret base underneath, and the main character fights elemental monsters that occur beyond the borders of human habitation. the areas are separated into the prime elements such as water, earth, air and fire along with mixed elements such as mud and lava.
My son was reading this at school in 2010/2011 and waiting for new publications at this time. He has confirmed that it is not ’The Edge’ series or ‘Monsters of the Earth’.

360H: Young Adult Book About Teenager who plays pool and lives in an abandoned factory/hanger (Solved!)

The book is relatively old (I read part of it around 2003 but it was published way before). The book was a young adult book that involved crime and a runaway that lived with two adults in what is either an abandoned factory or airplane hangar. The cover of the book I believe featured someone playing pool on it. The title might have been Me & (I can’t remember the rest). It was recommended to people that liked the Rag and Bone Shop and it was similar to the Westing Game. One thing I do remember clearly is that in the introduction the main character talks about how his dad can tell who has committed a crime or who has been to jail by just looking at them.

360G: Rivalry Turns Into Romance

The book I am searching for is a YA contemporary novel wherein the heroine has an ongoing academic rivalship with a male classmate, which eventually turns into something more even though she already has a boyfriend. I think the book was published in the range of 2017-now. The book cover is black, white, pink, and orange with illustrated faces on it, in a style that in my head is reminiscent of the cover of All Your Twisted Secrets by Diana Urban.
