^ Was that the BBC audio play of Kraken? I listened to that last weekend, it's part of what has prompted me to look at the above.
Of the list, I have copies of them all, but I've not read:
The Chrysalids (1955) The Seeds of Time (1956) short story collection Consider Her Ways and Others (1956) short story collection The Outward Urge (1959) Plan for Chaos (2009)
If people are interested this could be made a group read(?).
