Well, I started backwards but I read the first one in too. I didn't liked as much as I did with Strong Enough but it was good.
I liked Asher and Daniel and I liked how love the love for Daniel changed Asher without him even realizing it, but also how when he did realized it, he accepted those changes because the Daniel was more important than anything else.
It has its ups and down but it's a good story overall, what I really didn't like were Asher's violent tendencies. I hated it, but luckily that also changed and he asked for Daniel's forgiveness.
