Book 1: So You Want to be a Wizard?
Evading the school bullies, Nita takes refuge in the local library. Nostalgia overwhelms her as she browses in the children's section. Running her fingers along a collection of "So You Want to be a . . ." books one snags on her finger: "So You Want to be a Wizard". Nita takes the book home without hesitation and takes the Wizard's Oath printed therein and thus gets thrust into the world of wizardry. Along the way she stumbles upon Kit Rodriguez in the middle of a spell and together they get thrown into a parallel universe and face the Lone One 9the source of all entropy) on the Ordeal that every new wizard must face. When the Lone One threatens Manhattan, it will take all the knowledge Nita and Kit possess, plus a great deal of luck to be able to come out victorious. At least they have a white hole to help them!
A promising start to a series, worth a look at least. Whether or not it is as poignant as Harry Potter is difficult for me to determine because I read HP long before I heard of this series so I am probably a little biased. However, if you like HP, you probably will like this.
Book 2: Deep Wizardry
Nita and Kit get put on assignment while on vacation and join whale wizards in an ancient wizardry to re-imprison the part of the Lone One that was trapped a thousand years before. Nita's parents become suspicious of her sudden and lengthy disappearances with Kit and thus the teen wizards are forced to reveal their secret. It takes a good deal of convincing on top of the countless lives at stake. Big old Shark in this one!
Like Harry Potter, Nita and Kit are growing up and so are their challenges. Life or death is a big one and one of the most fundamental a person must face.
Book 3: High Wizardry
There is a new Callahan wizard, Nita's kid sister Dairine takes the Oath in secret and sets off on her Ordeal. Starting at and excessively high power level, her journey takes her far off into space where she awakens a planet that then begins to form sentient life. With great power comes great danger and it is not long before the Lone One targets Dairine. Nita and Kit are hot on her tail, though the Lone One has other ideas. It will take all the combines strength of Nita, Kit and Dairine to overthrow him this time. And a surprise Power that Be makes itself known!
Honestly, it was only a matter of time, Dairine hungers for knowledge and, until now, planned to be a Jedi. While the danger is no less, this really is not the best book in this collection.
Book 4: A Wizard Abroad
Nita gets sent to her aunt in Ireland because her parents want her to spend some time away from wizardry (impossible) and from Kit, but that doesn't mean Kit doesn't teleport himself there anyway. On her adventures, Nita not only discovers a surprising wizarding connection, but befriends countless other wizards and she unwittingly gets pulled into an ancient battle. Nita and Kit, together with their new friends and the help of the Sidhe, they must first reawaken three elemental weapons and then they must traverse into a dangerous parallel world and take on an ancient personification of their old adversary, the Lone One. Plus there is a kitten bard!
While Ireland is nice and ancient rivalries are pretty much requisite in fantasy (good vs. evil and all). This really is more about characters and the acquaintance with other (human!) wizards that until now had been limited to Nita, Kit, Dairine, and their advisors/area seniors Tom and Carl.
Book 5: The Wizard's Dilemma
A good read with just the right amount of desperation and author Diane Duane expertly separates the heretofore undefeated Nita-Kit (and later on Dairine, to a lesser extent) team so the reader can assuage just how much these wizards can do on their own. Pride and then Nita's mother's brain tumor separates the team for most of the story. Nita takes on trying to heal her mother alone, as Dairine lacks experience for the delicate work and Kit is busy working on a project with his dog, Ponch (which isn't that sensational since wizard's pets tend to develop a bit of 'weirdness') Nita and Kit are growing up and so are their choices. Before this ends they will both gather some new wisdom from a surprising source. Also, there is a pig.
Possibly one of the best novels in this collection. It is not as enthralling as "So You Want to be a Wizard" which has the draw of the introductory world, nor as directly dangerous as the other three. But this book has a greater depth than anything we've seen before, this time it is not Nita, Kit, and/or Dairine's lives at stake, nor even countless innocents, but Nita and Dairine's mother. All of the wizards must learn some very adult lessons which makes the themes in this series comparable to "The Order of the Phoenix" or "Half-Blood Prince" in the Harry Potter series.
