Spencer and the Younger Girl

I really liked Hadley in the first two books, so I was looking forward to reading her story and also - of course :) - curious about her personal hero. Spencer brings a lot of drama and angst to the table, so Hadley, with her positive and assertive personality, complements him well.
As is par for the course, the story is well written, and I enjoyed reconnecting with the “usual suspects” from the first two books: Charlotte and Jesse, Cassie, and especially Roman, who is definitely one of my favorite characters in the series.
It's “only” 4 stars for me, because the level of drama is just a bit too much for me, especially towards the end (was that really necessary?).
Not a spoiler, it has nothing to do with the storyline itself and as such is not relevant to the review, it's just a personal pet peeve of mine: Hadley had to wear a helmet on the four-wheeler, but not on horseback? I understand that wearing a helmet may seem "uncool", especially to teenagers, but really, it's just common sense. Even the nicest horse can stumble and throw you, through no fault of his or her own.
