Favourite Complete Book Series of 2015

Following on from my post about favourite stand alone books for 2015, here are my favourite book series of the year, the ones that  I have read the full trilogy/series.  I hadn't really concentrated much on particularly reading complete series/trilogies this year so I was very surprised with what I had read.  The list below is in no particular order of favourites, these are just ones that I rated very highly and would defiantly read again.  You may notice that there is one book missing from the Uglies series, Extras.  As mentioned in my review at the time, I was a little disappointed with this book as it did not seem to follow the story from the previous three books but instead started a new-ish story many years in the future.  For that reason I did not finish reading it (but will pick it up at some point in the future but wanted to read it when I couldn't remember so much about the first three books so I maybe view it as a separate story rather than attaching it to the series) and don't really consider it part of the series.

I have made a few changes reading wise this year from not concentrating too much on what's new out to read but reading books I have on my shelf or on my Kindle especially those that have been on there for quite a while.  The results have been very surprising.  Some I have loved and some I really have not cared for so much.    So here are the completed series that I loved this year.  If you haven't tried any of these, you should.  I highly recommend them... :-)

Tally is about to turn sixteen, and she can't wait. In just a few weeks she'll have the operation that will turn her from a repellent ugly into a stunning pretty. And as a pretty, she'll be catapulted into a high-tech paradise where her only job is to have fun.

But Tally's new friend Shay isn't sure she wants to become a pretty. When Shay runs away, Tally learns about a whole new side of the pretty world-- and it isn't very pretty. The authorities offer Tally a choice: find her friend and turn her in, or never turn pretty at all. Tally's choice will change her world forever...

 A love out of time. A spaceship built of secrets and murder....

Seventeen-year-old Amy joins her parents as frozen cargo aboard the vast spaceship Godspeed and expects to awaken on a new planet, 300 years in the future. Never could she have known that her frozen slumber would come to an end 50 years too soon and that she would be thrust into the brave new world of a spaceship that lives by its own rules.

Amy quickly realizes that her awakening was no mere computer malfunction. Someone - one of the few thousand inhabitants of the spaceship - tried to kill her. And if Amy doesn't do something soon, her parents will be next.

Now Amy must race to unlock Godspeed's hidden secrets. But out of her list of murder suspects, there's only one who matters: Elder, the future leader of the ship and the love she could never have seen coming.

In Beatrice Prior's dystopian Chicago world, society is divided into five factions, each dedicated to the cultivation of a particular virtue—Candor (the honest), Abnegation (the selfless), Dauntless (the brave), Amity (the peaceful), and Erudite (the intelligent). On an appointed day of every year, all sixteen-year-olds must select the faction to which they will devote the rest of their lives. For Beatrice, the decision is between staying with her family and being who she really is—she can't have both. So she makes a choice that surprises everyone, including herself.

During the highly competitive initiation that follows, Beatrice renames herself Tris and struggles alongside her fellow initiates to live out the choice they have made. Together they must undergo extreme physical tests of endurance and intense psychological simulations, some with devastating consequences. As initiation transforms them all, Tris must determine who her friends really are—and where, exactly, a romance with a sometimes fascinating, sometimes exasperating boy fits into the life she's chosen. But Tris also has a secret, one she's kept hidden from everyone because she's been warned it can mean death. And as she discovers unrest and growing conflict that threaten to unravel her seemingly perfect society, she also learns that her secret might help her save those she loves . . . or it might destroy her.

Vampires, werewolves, witches, shapeshifters -- they live among us without our knowledge. Night World is their secret society, a secret society with very strict rules. And falling in love breaks all the laws of the Night World.

In Secret Vampire, Poppy thought the summer would last forever. Then she was diagnosed with terminal cancer. Now Poppy's only hope for survival is James, her friend and secret love. A vampire in the Night World, James can make Poppy immortal. But first they both must risk everything to go against the laws of Night World.

Fugitives from Night World, three vampire sisters leave their isolated home to live among humans in Daughters of Darkness. Their brother, Ash, is sent to bring the girls back, but he falls in love with their beautiful friend.

Two witch cousins fight over their high school crush. It's a battle between black magic and white magic in Spellbinder.
