            .transforms(new CenterCrop(),new RoundedCorners(16))
            .into(holder.imageBook);

    holder.bookRating.setRating(this.bookList.get(position).getRating());
    holder.pages.setText(this.bookList.get(position).getPages());
}

The click listener should be added where you're binding the View to the ViewHolder object (onBindViewHolder). For getting the that object and launching your next activity though, passing a custom listener interface to get the clicked object with would be better. As the adapter shouldn't be responsible for launching activities via intents.

Hopefully that helps.
