Day 04 - Favourite book of your favourite series
Day 05 - A book that makes you happy
Okay, because I'm so rubbish, I'm putting the same book for both day 4 and 5. The book does apply to both categories but it just means I'm taking laziness to new levels.
Since I've just finished the recently released sixth Cassie Palmer book Tempt the Stars, I'm going for this one.
I could probably fit it for day 6 as well since I was extremely sad when it ended.
