The final action-packed instalment of the Spark trilogy.

Evie is out of options. She must comply with the Affinity Project – obey their rules, play their deadly games, give up Jamie. And her losses keep growing. When she decides to help a small group of Shields trying to affect change, Evie finds herself in the firing line. Counsellor Knox is intent on revealing her secrets and shackling her to the Affinity Project for life. To protect her family, Evie must betray those closest to her. The odds of success – let alone survival – are slim.


Rachael Craw began her working life as an English Teacher after completing a degree in Classical Studies and Drama at the University of Canterbury. She dabbled in acting, directing and writing for amateur theatre productions and small independent film ventures. Her passion for dialogue and characterisation finally led to long-form writing with the Spark series. Rachael's enthusiasm for classical heroes, teen angst and popular culture informs much of her creative process. She enjoys small town life at the top of the South Island of New Zealand where she lives with her husband and three daughters. Visit her online at


Overall, Shield has left me excited. I wasn’t sorry when I closed my review copy that it was all said and done, because Rachael Craw isn’t all said and done; her latest tight, confident crescendo work may end this series, but is not the grande finale. I am looking forward to what YA page-turner she delivers next.

Book Nerd Reviews

Spark, Stray and Shield are all enthralling reads, owing to a great mix of characters, carefully crafted supernatural elements and a killer plot. While each of the novels deal with heavy-handed issues there is always a sense of hope, which is achieved through the complexity of the characters and the strong relationships they have with one another despite their differences. I thoroughly enjoyed this series, and will undoubtedly revisit the world again.

Liz McShane

This is sci-fi at its best, where the technology comes second to the relationships involved, and we learn something about what it means to be human. Rachael Craw has created a compelling and exciting series. I closed the last page with tears in my eyes, sad to be leaving this world, but satisfied with the conclusion. I sincerely hope Rachael finds more stories in this world, but if this is all we get, then it’s enough.

You will be unable to put it down. This is a must-read, stand out series. I cannot recommend it enough.

Inside My Worlds

The final novel in the Spark trilogy is an intense, intelligent plot that will please young adult readers who like a challenging book to stretch their minds.

Mention in top ten YA list

The Herald Sun

From the young teenager we met in Spark to the strong, resilient woman that we see today, I loved Evie’s character development throughout the series.

Happy Indulgence

for teenagers over 16, I do recommend this very exciting book. I enjoyed it very much, though I did skim over the fight scenes.

Reading Time

The final instalment in the Spark Trilogy is absolutely breathtaking.

Diva Booknerd

Craw’s writing is fantastic. She maintains an almost frantic pace throughout the series and never drops the intensity or suspense.

The Book Kat

Craw’s descriptive writing takes you right into the heart of each scene in a very visceral way (again, that basement scene – gut = wrenched). Like others have noted, it’s so easy to imagine these on the big screen.
