We Were Liars is fascinating. The writing style is very concise, and while there is fabulous description of the island that the Sinclairs occupy every summer, there's also an underlying eerie note that makes it all the more interesting to read about. The setting seems intricately real, what with the shimmering waters and the seashells and ice cream. Cadence, Mirren, Johnny, and Gat are easily distinguishable and entertaining. The gradual family tension among the Sinclairs is well-developed, and the plot twist at the end had me reeling.
However, I definitely didn't like this book right from the start. The writing is a bit peculiar and jerky at times, and Cadence (who narrates the story) seemed quite whiny. I did warm up to the novel once more problems were woven into the plot. Sometimes, though, there was a weird feeling, as if these problems weren't as big as they really were. For example, the twist at the end was executed in an almost anticlimactic way. It's sort of just...confusion for a few chapters or so. Once I understood, though, I really liked the ending.
Overall, I would definitely recommend this book as a lighter read, though I did have a few problems with it. The descriptions are marvelous and the overall idea is very unique.
