I guess it all depends on how much you've learnt during these six months.
Assuming a slow paced progression, finding readable stories at this level might be hard. One solution could be to use the key of basic composition manuel (here
for example). Thus you have a supply of easy, short sentences to read. The drawback is of course that the first exercises are not continuous stories and therefore it might not be very enjoyable. To avoid this maybe you could also have a look at Frost
or both books by Sidgwick, First Greek Writer key
and Greek Prose Composition key
As far as stories are concerned, I'd like to mention Chambers, The Greek war of independence
. It narrates, in Attic Greek, the Greek war of independence (1821-1827) and, as it was meant to be used as a first Greek book, it provides notes, a grammatical summary and a glossary at the back of the book. I found it an enjoyable read but perhaps it will be too hard at your level.
Edit. There is also Edward's Salamis in easy Greek
. The author mentions it was written written with (1913) 2nd year students of Greek in mind but maybe you'll find it suitable now or in some weeks/months.
