Shiver question

I wouldn't replace, I would erase Cole and Isabel. No, scratch that. I would delete Linger and Forever. It's not that I don't like Cole and Isabel, I do, and I think they are so funny, they always crack me up. The thing is that when I read Shiver I loved how cosy it felt, if you know what I mean. I guess you don't cause I don't make sense. Ugh. Anyway, reading Shiver felt like a fluffy blanket, everything was so simple and cute, not many characters, just Sam and Grace and fluffiness all over the place... I fell in love with this. But when I read Linger, I was introduced to two new main characters, Cole and Isabel. And just like that the story didn't feel cosy anymore, the plot got complicated and overdramatic, I mean really? Grace's parents acting like total pricks was the biggest problem ever? I don't know, call me weird but I think that Shiver didn't need to be a trilogy.

I agree i loved the fact that in shiver it was just sam and grace but if i could replace a character it would be shelby
