Need help with Jodi Picoult books..?

So latley I've been loving Jodi picoults books I've read the tenth circle, nineteen minutes, mercy, harvesting the heart, plain truth and currently reading handle with care. Tell me if it's worth finishing.. My favs are 19 minutes, tenth circle, and plain truth, I was wondering if songs of humpback whales was any good, and I've also been dying to ready the pact, so I wanted to know if that was good to? Please don't say anything about my sisters keeper I already know about it. Thank you.
