I read all 5 as I wanted to get some insight on what my son will be reading, so I can answer his questions etc... I did realise I would be learn anything here too! But I did haha, I love these books! You left me eager for more that's for sure - I was about to suggest the next books be made longer, however, I've got to remember the target audience is 'well' below my age group... And in saying that maybe not? Actually I'm sure 'most' non investment type people would gain a lot from reading these great little books. Well done! Keep them coming!
