Books like Double Cross

I enjoyed this book but I think the series should have ended on the last book as this one seemed pretty unnecessary and didn't add much to the overall series.Double Cross was definitely good but it was my least favourite out of the series as it follows a pretty irrelevant character,Callie's best friend,Tobey.I did enjoy the story but I feel it would have been better as a stand alone and not associated with the series.The book was still fantastic as Malorie creates an amazing story again while still providing character depth and generating interest for their well being.However,I would have loved to see more Sephy,Meggie and Callie.Great book but personally I thought it was pretty irrelevant to the series.I would definitely still recommend it though.
