Five stars! This one I like as I have SUCH a pet peeve about siblings in media. Very rarely are they accurate portrayals of siblings and NO ONE calls their sibling 'sis/bro', that's weird. 

Anyway... deep breaths, we'll fix it one book at a time XD 

"Very enjoyable read, the characters are easy to empathise with and there's funny moments that the siblings have are very relatable and they actually sound like siblings not cliché. Highlights the importance of true family and chosen family"
