I think fans of Slammed might like this book. It’s by no means the same storyline, but it shares a similar feeling. Although its more 'tame'… very strongly YA. Dai, K. et al.

I had plans, and those plans did not involve kissing her against my car. Dammit, she was going to kill me. “Congratulations, it’s yours.”Lebens-Higgins, Z. W. et al.

Echo’s reliance on her ‘popular’ friends at school and her need for their approval didn’t really sit right with me… but at the same time, I guess it was an understandable feeling for someone in high school. I just wish it hadn’t been so important to her…. And I also would have wished for an epilogue. The book has a happy-for-now ending (and a sequel featuring some of the secondary characters on the way) but after all the heart ache in the book, I still would have liked a glimpse maybe 5 years into the future so see how things had worked out for them.

Holy SHIT! Your book’s good, ma’am. Oishi, M. et al. Direct observation of reversible charge compensation by oxygen ion in Li-rich manganese layered oxide positive electrode material, Li 1.16Ni 0.15Co 0.19Mn 0.50O 2. J. Power Sources 276, 89–94 (2015). At their first tutoring session, Noah attempts to storm out of the room. Echo moves to stop him, and Noah sees her scars. Since the scars are not common knowledge at school, Echo is worried that Noah will gossip about her. Her best friend, Lila, encourages her to take control of the rumor, but Echo refuses because she is concerned about her lost memories. However, the girls are surprised when Noah keeps what he knows to himself. The muscles in his shoulders visibly tensed. “I watched you battle against the worst memory of your life and I watched you win. Make no mistake, Echo. I battled right beside you. You need to find some trust in me … in us.” Combining love and loss, friendship and family, the unfairnesses of life and the determination to overcome them, Pushing the Limits is a book that is not only to be read, but cherished. This is one gem that shines!

If I was judging Pushing the Limits solely based on the journey of the characters and how they struggled to reach their own personal victories, I would have gone 4 stars on the book. This was a great story. I like to see characters with depth and grit. It's always fascinating to watch people push past their inner demons and come out on the other side to start their healing process. Both Noah and Echo were inspirational characters who learned not only how to work on themselves, but also learned how to encourage each other to trust again. Wu, J. et al.
