This has been a wonderful feel-good series about friendship, love, families, life and how they all come together. Feels magical. Written in a playful manner yet as you brush it's surface , you realise it's deep enough for you to be touched, to learn about life.
I won't add much more except this one quote which I loved in the 3rd book. It is sprinkled with this and many more:
".....This was the future. Life would get busier and more varied, populated both by beautiful things and unfortunate circumstances. If their friendship demanded exclusivity or solitude, it couldn't work. If it required that everything go as planned, it would turn brittle, and ultimately it would break. On the other hand, she knew that if they could be flexible and big, if they could encompass change, then they could make it....... "
This is true for every relationship nowadays. and that's good but also kind of sad, even if illogically so.
