Guess the Plot
Worlds Collide
1. Tiffani is a ballet dancer; Brandon is a stevedore. She loves arts and crafts pottery. He loves NFL football. They meet by happenstance and discover a mutual passion: both are serial killers.
2. Anna finds a mysterious cave that pulls her into a world inhabited by strange creatures who think her appearance represents the beginning of an invasion. Which is pretty much how Anna felt when the Roman Empire first invaded her country.
3. Something is headed straight toward Earth, with the resulting crash enough to wipe out all of humanity. However, unlike an asteroid, this is another planet with life of its own. Hey, if we all gotta die, we might as well take someone with us.
4. When a portal opens between earth and fantasy land, it's not young teens who move through, it's the whole planet. To set things right, Grandma McCurdy must face increased gravity, tidal anomalies, climate change, invasive species, etc. Oh, and cataclysmic magic.
5. When opposing candidates for the office of mayor meet at the Worlds Collide bar, sparks fly, leading to a whole nother level of heat in their respective campaigns.
6. When a world of (really hot) vampires, werewolves and mummies collides with a world of discontented (and also really hot) high school students, the results are predictable yet strangely compelling.
7. The studios want something "new, but familiar," so Harvey writes a dystopian version of the 1950s classic When Worlds Collide that sees scientists murdered by mobs of zombies, a rocket crashing into the sun, and another ship piloted by Jennifer Lawrence and Lady Gaga making it to safety. Sure, Harvey gets a contract, but will he get a date with Jennifer?
8. The land of rainbows and sunshine collides with the world of zombies and darkness when a mishap with a happy-smile potion goes terribly wrong. Can Sparkles and Kazoo find a cure before their home is irrevocably changed forever?
9. Minky Flint wants to marry a hard working farm boy instead of the foppish prat her parents engaged her to before she was born. Fortunately, she has a fairy godmother. Unfortunately, the godmother agrees with her parents! What's a girl gotta do to get the right fairy tale ending?
Original Version
Worlds Collide is the first book in a Mid-Grade fantasy series complete at 35K words set in the time period of [during] the Roman occupation of the Britons. [My sources (Wikipedia) tell me the occupied area is known as the Britains or Roman Britain. The Britons are the people. Also, you might manage to say the book is 35K words, rather than the series is 35K words, and that the series is set during the occupation, rather than the words are set then. It'll be easier if you use two sentences to convey the information.]
Anna starts her life as a happy child with loving parents. She and her family live in a small village that goes unnoticed by both the Romans and the Saxons who are fighting with each other for control of the land. Anna's happiness is cut short by the death of her father and shortly after that, the death of her mother. [when her parents die and she must move in] She lives for several years with her drunken uncle. until the day fate crosses her path.
[Years later,] Anna finds [stumbles upon] a mysterious cave that pulls her into a new world inhabited by strange creatures, who are just as surprised to see her as she is to see them. [It would be nice to know whether Anna is ten or thirteen or sixteen.]
There is a priestess among the people of this new world who is able to help[s] Anna to understand them and them her. [Are the "people" of this world the same beings you described as "strange creatures"? If so, calling them people may give the wrong impression. If not, then I don't see the arrival of one girl causing as much distress as it does in the next paragraph.] Anna is brought before King Maaz of the Suan’s [Suans] and after she tells her story, the king decides that she is telling the truth and is no threat to his people.
With all societies in this world or another, things aren’t always as they seem. Saban, one of the kings [king's] closest generals had [, has] been working for a long time to steal the loyalty of the kings [king's] rangers, and seize power for himself,[.] [He] sees Anna as a tool he can use to further his ambitions.
With the help of the kings [king's] treacherous oldest son[,] the general is able to overthrow[s] King Maaz and have [has] him arrested.
Anna finds herself a fugitive on the run with a small group of Suan’s [Suans] who are loyal to King Maaz. They desperately need help but don’t know who they can trust, so they attempt something that may cause two worlds to collide in war. ["Attempt something" is too vague. What's their plan? This is more important information than anything about Anna's parents and her drunken uncle and the priestess.]
Notes
Sentences that logically belong together should be in the same paragraph. Using a lot of one-sentence paragraphs gives the impression you're listing ideas without connecting them. Your plot summary could easily be organized into three paragraphs.
As the Roman occupation lasted about 370 years, telling us the story is set in that time period is like telling us a story is set in the time between the pilgrims reaching Plymouth Rock and the debut of The Simpsons on Fox. We have a right to know whether this is set at the time Hadrian's Wall was being built or closer to when the self-proclaimed emperor Carausius was assassinated by his treasurer.
