The Guardians of Time Trilogy  by Marianne Curley is an interesting mix of Sci Fi ideals mixed with a mythological background. Set in Australia the book follows teenagers and immortals who are charged with protecting history from a chaos maddened goddess. The trilogy is different then most due to its many twists and turns. I personally was able to guess some things, but then other plot devices completely through me for a loop. There is enough romance in the books that if you liked the Twilight series , you will probably like this one. The story is told from male and female perspectives, so it's not so out there for guys to like them as well. If you like the Cornelia Funke's Ink trilogy , you also stand a good chance at liking this series. Give it a go, and then tell me what you think.
