Boring and predictable. It sounded so cute, but the formula was the regular standard. Simple and uninventive. Drama for the sake of drama, jealousy for the sake of jealousy, the same old story you would usually read. I kept reading, hoping it would get better, but nope. The ending was super cheesy too. I'm all for happy endings, but there is a point where it's too much lactose. It felt more like reading young-written fanfiction than anything that would've actually been published. If it weren't for the "hot guy makes a bet to sleep with the girl" trope, I would say it would be cute for tweens, but I personally feel like sex needs to wait for the teenage years, tweens still need more growing.
Cute enough for a quick read of no substance, but otherwise I would avoid it.
