I've got titles from Level 1 to Level 5. I think my 7 yr old girl has more interest on Level 2 - 4 while Level 5 is too difficult. Since I just bought those in a month's time, she still need longer time to read.
If you want those books, you can order through this web, usually has some discount even the books are not shown. (they will send you a book list to choose from)
I think it's an easy-to-read series of books as there are many topics to choose from & the levels are in progressive stages. Personally I think they are more practical than Oxford Reading Tree as the wordings are more common in daily use & with bigger prints too. Also, the pictures are more attractive too!
You can ask them to send you a full-list to choose from. If you buy more, you may check if they got further discount or return gifts etc. I quite like buying books here as they have payment upon delivery.
I've checked from the website as you mentioned. Unfortunately, I found I could not locate the search function. And the only step into reading that I found from storybook icon was thomas series. Should that be more that that in one series?
Yes, there are more like Strawberry Shortcake (also under story book). If you need more, you can ask them for a booklist. click 'here'www.ngatinggroup.com.hk
